Effects of elastic foundation and the Poisson’s ratio on the nonlinear buckling and postbuckling behaviors of imperfect FGM plates subjected to mechanical loads

This paper presents an analytical approach to investigate effects of elastic foundation and the Poisson’s ratio on the nonlinear buckling behavior of imperfect FGM plates, subjected to mechanical loads. Material properties are assumed to be temperature independent, and graded in the thickness direc...
