Post-Buckling Analysis of Laminated Composite Doubly Curved Panel Embedded with SMA Fibers Subjected to Thermal Environment

In this article, thermal post-buckling of laminated composite panel with SMA subjected to uniform temperature change is investigated. The panel model is derived taking the geometric nonlinearity in Green-Lagrange sense based on the HSDT and then it is extended to incorporate the material nonlinearity arises due to temperature in the SMA via marching technique. The panel is discretized using nonlinear finite element. The system equations are developed by minimizing the total potential energy of the system and solved by a direct iterative method. The effects of different parameters are examined in detail and the results are compared with the published results.
