Non-linear analysis of functionally graded fiber reinforced composite laminated plates, Part II: Numerical results

In this Part, the extensive parametric studies performed are reported and numerical results are presented for the non-linear vibration, non-linear bending and compressive postbuckling of uniformly distributed and functionally graded fiber reinforced unsymmetric cross-ply and/or antisymmetric angle-ply laminated plates resting on Pasternak elastic foundations under different hygrothermal environmental conditions. The numerical results show that the functionally graded fiber reinforcement has a significant effect on the postbuckling response and load-bending moment curves of plate bending, whereas this effect is less pronounced on the load-deflection curves of plate bending and the linear and non-linear frequencies of the same plate.

► FG fiber reinforcement has a significant effect on the postbuckling response of the plate. ► FG fiber reinforcement has a significant effect on the bending moment of the plate. ► FG fiber reinforcement has a small effect on the bending deflection of the plate. ► FG fiber reinforcement has a small effect on the linear and non-linear frequencies of the plate.
