Static buckling analysis of shape memory alloy reinforced composite laminated plate

Abstract

Abstract With high strength and stiffness composites are being widely used as structural materials. The properties of composites can further improve by reinforcing with advanced structural components like shape memory alloys (SMA). In the present study nonlinear buckling analysis of laminated composite plate with layer of shape memory alloys are done. Finite element governing equation based higher order shear deformation theory with principle of virtual work is considered. Properties of composite plates are formulated with micro-mechanical approach. A MATLAB program is developed with nine nodes isoperimetric element. Influence of volume fraction of SMA, recovery stress, with and without SMA layer, with temperature on critical buckling load is revealed. Convergence and validation study presented here shows the exactness and efficiency of the model.
