Stability and Free Vibration Behaviour of Laminated Composite Panels Under Thermo-mechanical Loading

Abstract

In this article, the free vibration and the buckling (mechanical and/or thermal) behaviour of laminated composite flat and curved panels are analysed numerically. Simulation model has been developed using ANSYS Parametric design language code in the ANSYS environment. The convergence behaviour of present finite element results have been checked and comprehensiveness of the model is revealed by comparing the results with those available published literature. Wide variety of numerical examples is solved for different parameters such as lamination schemes, support conditions and material properties under the thermo-mechanical load to highlight the applicability of the present simulation model. It is finally understood that the proposed model is capable of solving the mechanical responses (free vibration and buckling) of orthotropic materials accurately with very less computational cost under the combined action of loading.
