Optimum critical buckling of functional graded plates under non-linear temperature by using imperialist competitive algorithm

Abstract

This paper presents an approach to optimization of critical buckling temperature based on imperialist competitive algorithm (ICA) for functional graded plates (FGP) to non-uniform distributed temperature load. The objective is to maximize the critical temperature capacity of a functional graded plate. The third-order shear deformation theory is used in the mathematical formulation. The numerical results reveal that the imperialist competitive algorithm (ICA) can efficiently minimize critical buckling under non-linear temperature on the FG plates.
