Buckling Analysis of Thin Frp Laminate Under Combined Thermal and Mechanical Loading

Thermal environment influences the buckling behavior of structures, in addition to the mechanical loads acting on it. The present work aims to predict the buckling load factor of thin FRP laminates subjected to pressure and temperature loads. The problem of thin FRP laminate in the form of rectangle is simulated in finite element software ANSYS using 2-D finite element method that works on classical lamination theory. Two different stacking arrangements; (i) symmetric cross ply and (ii) symmetric quasi-isotropic of E-Glass-Epoxy with Fiber volume fraction, Vf = 0.55 and Kevlar-Epoxy with Fiber volume ratio, Vf = 0.60 are considered in the analysis, and the influence of in-plane aspect ratio (AR) and thickness ratio (TR) on buckling factor is studied.
