Abstract

Abstract

Based on the RayleighRitz theory and the finite element method, the expressions of critical buckling loads on thin plates under thermomechanical coupling loads was derived. Under simultaneously imposed mechanical and thermal loads, the finite element program was compiled in the MATLAB environment to solve the buckling critical loads on thin plates. In the buckling analysis, the thermal load was applied at the nodes in the form of temperature field. The effects of mechanical load components and thermal load components on the instability of thin plates were analyzed through nonuniform temperature field loading. The results show that, with the increase or decrease of given thermomechanical loads, the critical load increases or decreases almost linearly.
