Abstract

In this study, for the first time, the buckling of relatively thick composite plates with shape memory wires and with an extended attached mass was investigated. The main theory used in this research is Kant's 9th-order shear theory. The attached mass in this study is a composite sheet located in the middle of a rectangular multilayer composite sheet, and nitinol shape memory wires in the main composite plate were embedded In this paper, for the first time, the effects of applying shape memory wires in a composite plate and an extended attached mass on the plate buckling force have been investigated. The Galerkin solution method to solve the equations was used. The results of this study showed that for a shape memory composite plate with a attached mass in the middle with high-order shear theory, the critical buckling load increases with decreasing A/aa ratio (Increasing the dimensions of the attached mass). The buckling force of the memory wires also increases linearly with the increase in the volume fraction.
