Fractional calculus has been the target of the work of many mathematicians for more than a century. Some of these investigations are of inequalities and fractional integral operators. In this article, a novel fractional operator which is known as weighted generalized proportional Hadamard fractional operator with unknown attribute weight is proposed. First, a fractional formulation is constructed, which covers a subjective list of operators. With the aid of the above mentioned operators, numerous notable versions of Pólya-Szegö, Chebyshev and certain related variants are established. Meanwhile, new outcomes are introduced and new theorems are exhibited. Taking into account the novel generalizations, our consequences have a potential association with the previous results. Furthermore, we demonstrate the applications of new operator with numerous integral inequalities by inducing assumptions on weight function ϖ and proportionality index φ. It is hoped that this research demonstrates that the suggested technique is efficient, computationally, very user-friendly and accurate.

Functionally graded materials (FGM) are an advanced composite material class whose vary gradually and continuously in the composition of microstructure constituents through the dimension of the material [1,2,3]. The behavior composition of FGM reduce the structural weight with increasing its coefficient modulus of stiffness and strength [4,5,6,7,8]. The properties of all constituents can be employed, for example, the toughness of a metal can be mated with the refractoriness of a ceramic, without any compromise in the toughness of the metal side or the refractoriness of the ceramic side [9,10,11,12,13,14]. The simple rule of mixture (Voigt law) is used to obtain the effective micromechanics material properties in the commencement of research papers. But to assess the effect of the micromechanical models on the structural responses of FG plates several micromechanical models of FGMs have been studied in [14,15,16]. Gasik has studied different micromechanical models to obtain the effective material properties of FGMs with power-law, Sigmoid, and exponential function distributions of volume fraction across the thickness of the static, buckling, free and forced vibration analyses for simply-supported FG plates resting on an elastic foundation [17]. Akbarzadeh et al. [18] have investigated about the influences of different forms of micromechanical models on FGM pressurized hollow cylinders. They have used the numerical results via finite element method (FEM) analyses for detailed and homogenized models of functionally graded (FG) carbon nanotube reinforced composite (CNTRC) beams. The effect of the imposed temperature field on the response of the FGM plate composed of Metal and Ceramic with the Mori–Tanaka micromechanical method is discussed [19,20].
Shen et al. [21] have studied the small and large amplitude frequency of vibrations are presented for a functionally graded rectangular plate resting on a two-parameter elastic foundation with two kinds of micromechanics models, namely, Voigt model and Mori–Tanaka model. The comparison studies reveal that the difference between these two models is much less compared to the difference caused by different solution methodologies and plate theories. In literature there is no available work treating the impact of the homogenization models on the sandwich FGM plate. In this paper we have studied the impact of (Reuss, LRVE, Tamura) homogenization or micromechanical models on the axial and shear stress of sandwich functionally graded materials plate subjected to linear and nonlinear thermal loads. The static and elastic behavior of the simply supported is considered. Using an integral higher shear deformation theory (HSDT), the governing partial differential equations are solved in the Cartesian coordinate via Navier solution method. Those Numerous micromechanical models have been examined to attain the effective material properties of the two-phase FGM plate (Metal and ceramic). The numerical results are compared with those given by other model existing in the literature to confirm the accuracy of the (HSDT). The present results are in good agreement with all models studied of homogenization for all values of the material index and all geometry configurations of the FG-sandwich plates.
The geometry domain is assumed as a uniform rectangular plate with thickness "h", length "a", and width "b" as shown in Figure 1. The plate has three layers. The FG-face sheets are made by two materials metal and ceramic.
The mechanical and thermal proprieties of Metal (Titanium) are Young modulus E(z) is 66.2 GPa, thermal expansion coefficients α is 10.3 (10−6/K). The mechanical and thermal proprieties of Ceramic (Zirconia) are Young modulus E(z) is 117 GPa, thermal expansion coefficients α is 7.11 (10−6/K). The Poison coefficient is supposed the same in the metal and the ceramic (ν is 1/3). In the following.
Several types of geometries configurations are exanimated depending the thickness of each layer as shown in Table 1.
Configurations of the plate | Geometries with Layers thickness |
(1-0-1) | ![]() |
(1-1-1) | |
(1-2-1) | |
(2-1-2) | ![]() |
(2-2-1) |
The volumes fraction of the FG- faces sheet are assumed varies as following functions (Eq 1).
V(1)=(z−h0h1−h0)kz∈[h0,h1]V(2)=1z∈[h1,h2]V(3)=(z−h3h2−h3)kz∈[h2,h3] | (1) |
Where K is the material index.
A number of micromechanics models have been proposed for the determination of effective properties of FGMs. K is the material index.
(1) Voigt model
The Voigt model is relatively simple; this model is frequently used in most FGM analyses estimates properties of FGMs as:
P(T,z)=Pc(T,z)V(z)+Pm(T,z)(1−V(z)) | (2) |
(2) Reuss model
Reuss assumed the stress uniformity through the material and obtained the effective properties as:
P(T,z)=Pc(T,z)Pm(T,z)Pc(T,z)(1−V(z))+Pm(T,z)V(z) | (3) |
(3) Tamura model
The Tamura model uses actually a linear rule of mixtures, introducing one empirical fitting parameter known as "stress-to-strain transfer". For q = 0 correspond to Reuss rule and withq=±∞to the Voigt rule, being invariant to the consideration of with phase is matrix and which is particulate. The effective property is found as:
P(T,z)=(1−V(z))Pm(T,z)(q−Pc(T,z))+V(z)Pc(T,z)(q−Pm(T,z))(1−V(z))(q−Pc(T,z))+V(z)Pc(T,z)(q−Pm(T,z))withq=σ1−σ2ε1−ε2 | (4) |
(4) Description by a representative volume element (LRVE)
The LRVE is developed based on the assumption that the microstructure of the heterogeneous material is known. The input for the LRVE for the deterministic micromechanical framework is usually volume average or ensemble average of the descriptors of the microstructures.
The effective property is expressed as follows by the LRVE method:
P(T,z)=Pm(T,z)(1+V(z)11−Pm(T,z)Pc(T,z)−3√V(z)) | (5) |
Based on the same assumptions of the conventional HSDT (with fives variables or more). The displacement field of the proposed HSDT is only with four unknowns variables and can be written in a simpler form as:
{u(x,y,z)=u0(x,y)−z∂w0∂x+k1f(z)∫θ(x,y)dxv(x,y,z)=v0(x,y)−z∂w0∂y+k2f(z)∫θ(x,y)dyw(x,y,z)=w0(x,y) | (6) |
Where u0(x,y), v0(x,y), w0(x,y), and θ(x,y) are the four-unknown displacement functions of middle surface of the FG-sandwich plate. f(z) is the warping function and (k1 and k2) are constants.
In the current research work the proposed combined (exponential/hyperbolic) warping function ensures the nullity condition of the free surfaces of the FG-sandwich plate (zero transverse shear stresses at top and the Bottom of the FG-sandwich plate). The present exponential/hyperbolic warping function f(z) is expressed as:
f(z)=[ln(πexp(120))−((0.1407)(5/6))cosh(πz)]z | (7) |
The stresses/strains linear relation of the PFG-sandwich plate can be expressed as:
{σxσyτxyτyzτxz}(n)=[C11C12000C12C2200000C6600000C4400000C55](n){εx−αTεy−αTγxyγyzγxz}(n) | (8) |
Where
{C(n)11=C(n)22=E(n)(z)1−(v(n))2C(n)11=v(n)C(n)11C(n)44=C(n)55=C(n)66=E(n)(z)2(1+v(n)), | (9) |
The variation of the temperature field across the thicness is assumed to be:
T(x,y,z)=T1(x,y)+zhT2(x,y)+Ψ(z)hT3(x,y) | (10) |
Where
Ψ(z)=hπsin(πzh) | (11) |
The principle of virtual works of the considered PFG-sandwich plates is expressed as δ U+δ V=0 where δUis the variation of strain energy; and δV is the variation of the virtual work done by external load applied to the plate. The governing equations can be obtained as follows:
{δu0:∂Nx∂x+∂Nxy∂y=0δv0:∂Nxy∂x+∂Ny∂y=0δw0:∂2Mbx∂x2+2∂2Mbxy∂x∂y+∂2Mby∂y2=0δθ:−k1Msx−k2Msy−(k1A′+k2B′)∂2Msxy∂x∂y+k1A′∂Ssxz∂x+k2B′∂Ssyz∂y=0 | (12) |
Based on the Navier method, the following expansions of displacements are
{u0v0w0θ}={Ucos(αx)sin(βy)Vsin(αx)cos(βy)Wsin(αx)sin(βy)Xsin(αx)sin(βy)} | (13) |
where (U, V, W, X) are unknown functions to be determined and α=π/a and β=π/b.
In the present work, the transverse temperature loads T1, T2, and T3 in double sinus series form as:
{T1T2T3}={ˉT1ˉT2ˉT3}sin(αx)sin(βy) | (14) |
The closed-form solution can be written as following matrix form:
[S11S12S13S14S12S22S23S24S13S23S33S34S14S24S34S44]{UVWX}={P1P2P3P4} | (15) |

Where and (LT,aLT,RT) are coefficients calculated by integral summation formulations, in which ˉz=z/h,ˉf(z)=f(z)/h and ˉψ(z)=ψ(z)/h.
In the following three sections, the results have been presented.
A comparison has been done to verify the accuracy of the present theory of different models of homogenization (Reuss, Tamura and LRVE). Results are compared with the mixture model (Voigt) using by Zankour and Algamidi [22].
The dimensionless transverse and normal stress are expressed as:
{ˉσx=h2α0ˉT2E0a2σx(a2,b2,h2)ˉτxz=10hα0ˉT2E0aτxz(0,b2,0) | (18) |
with E0=1GPa and α0=106K.
Table 2 presents the variation of dimensionless axial stress "ˉσx" of the square FG-sandwich plate subjected to linearly thermal load "T3=0" versus volumes fractions (material index "k") for different values of layer thickness ratio. It is remarkable that there is a proportional relationship between the index "k" the dimensionless normal stress "ˉσx".

In this section, the parametric studies are presented in the explicit graphs form. Figure 2 plots the variation of the axial stress "ˉσx" across the total thickness "h" of FG-sandwich plate (k=1) under linear thermal loads "T3=0" with different micromechanical models. From the plotted graphs, it is clear that the compressive stresses are obtained at the top of the plate. We can see that the present results are in good agreement with different models Voigt, Reuss, LRVE and Tamura for configurations of the FG-sandwich plate (1-0-1, 1-2-1 and 2-2-1) and the material index k=1 (Figure 2a–c).
Figure 3 illustrates the variation of the "ˉτxz" through the total thickness of the 1-0-1, 1-2-1 and 2-2-1 FG-sandwich plate under linear thermal loads "T3=0". It is noted that the shear stress "ˉτxz" is parabolically varied through the total thickness of the FG-sandwich plate. We can see that the present results are in good agreement with different models Voigt, Reuss, LRVE and Tamura for configurations of the FG-sandwich plate (1-0-1, 1-2-1 and 2-2-1) and the material index k=1(Figure 3a–c).
In the present section three types of the temperature distribution across the thickness are considered. The first one, the temperature is linearly distributed through the thickness T=zT2, in the second type the temperatures vary nonlinearly across h (T=zT2+ψ(z)T3) and the third type is reserved for a combination of linear and nonlinear distributions T(z)=T1+(z/h)T2+(Ψ(z)/h)T3.
Figure 4a shows the distributions of the axial stress "ˉσx" through the total thickness of the simply supported 2-2-1 FG-sandwich plate for various values of the thermal load (T1=100), T2=100 and T3=100 with (k=1). From the plotted curves, it can be observed that the axial stress "ˉσx" is c influenced by the values of the thermal load.
Figure 4b plot the variation of the shear stress "ˉτxz" through the thickness h of the 2-2-1 square FG-sandwich plate (k=1). For different values of the thermal load (T1=100), T2=100 and T3=100. It can be noted from the graphs that the shear stress "ˉτxz" has a parabolic variation through the thickness. The maximal values of the shear stress "ˉτxz" are obtained at the mid-plane axis "¯z=0". And it is clearly influenced by the values of the thermal load.
In this investigation, the impact of (Reuss, LRVE, Tamura) homogenization or micromechanical models on the axial and shear stress of sandwich functionally graded materials plate subjected to linear and nonlinear thermal loads have studied. The static and elastic behavior of the simply supported is considered. Using an integral higher shear deformation theory (HSDT), the governing partial differential equations are solved in the Cartesian coordinate via Navier solution method. Those Numerous micromechanical models have been examined to attain the effective material properties of the two-phase FGM plate (Metal and ceramic). The numerical results are compared with those given by other model existing in the literature to confirm the accuracy of the (HSDT). The present results are in good agreement with all models studied of homogenization for all values of the material index and all geometry configurations of the FG-sandwich plates.
