Reinvestigation of Intuitive Approach for Thermal Postbuckling of Circular Plates

摘要

Study of thermal postbuckling behavior of structural members such as columns and plates subjected to thermal loads is necessary in the design of aerospace structures, as one can use the postbuckling load-carrying capacity for obtaining efficient designs. It has also been shown through rigorous continuum and finite element (FE) formulations in the works of Thompson and Hunt [1], Dym [2], Rao and Raju [3,4], and Raju and Rao [5] that the thermal postbuckling load-carrying capacity of the aforementioned structural members is an order of magnitude higher than the load-carrying capacity subjected to mechanical loads. Recently, this complex thermal postbuckling phenomenon has been investigated through intuitive formulations that give simple and reliable closed-form solutions.
