Stability Analysis of Rectangular Thin Walled Structure under Nonlinear Distributed Stress

Abstract:

The stability of rectangular thin wall with 3 simple supported sides and 1 free side, subjected to nonlinear distributed stress, is analyzed. Galerkin method is applied in order to study the internal relationship between the critical thickness and nonlinear stress. Under the same stress circumstance, as the a/b ratio gets larger, the critical thickness for the thin wall structure getting buckled grows too. The influence of different material properties on the critical thickness is also researched. The method proposed in this paper is applicable for more complicated distributed stress and also can provide some reference criterion for design of thin wall structure.
