Post buckling response of laminated composite plate on elastic foundation with random system properties

FEM model for stochastic mechanical and thermal postbuckling response of functionally graded material plates applied to panels with circular and square holes having material randomness

“…Onkar et al [24] investigated the generalized buckling of laminated composite circular cut-out plate with random material properties using classical plate theory (CLT) combined with FOPT. Singh et al [25] investigated the effect of random system properties on the post-buckling of laminated composite plates supported with elastic foundation using HSDT based C 0 nonlinear FEM combined with direct iterative procedure in conjunction with FOPT. Jagtap et al [26] presented the stochastic nonlinear free vibration response of elastically supported FGMs plates with random system properties with temperature independent (TID) and dependent (TD) material properties via on higher order shear deformation theory (HSDT) with von-Karman nonlinear strains using modified C 0 continuity in conjunction with FOPT.…”

Stochastic vibration characteristics of finite element modelled functionally gradient plates

“…10 and 11, respectively. The analysis is performed with temperature dependent material properties of Titanium oxide and Zirconia with different volume fraction indices, n. The top surface of the plate is maintained at 400 K, while the bottom surface remains at 300 K, and the side to thickness ratio, ða=hÞ is taken as 10 it can be anticipated that the dispersion of the frequency parameter increases linearly with the dispersion in the material properties. It is found that the frequency parameters have mostly influenced by E c when only individual material property varies by keeping other system parameters constant to their mean values for both the clamped and simply supported boundary conditions.…”

“…Singh et al [10] studied the second order statistics of post buckling load of shear deformable laminated composite plates resting on linear elastic foundation with random system properties. The formulation is based on higher order shear deformation plate theory in general von Karman sense.…”

Bending of a fiber-reinforced viscoelastic composite plate resting on elastic foundations

“…Let the plate be subjected to a transverse load and be attached to the foundation so that no separation takes place in the process of deformation. The interaction between the plate and the supporting foundation follows the two-parameter Pasternak's model as w [5][6][7]11] where…”
