Collapse behavior of thin rectangular plates subjected to partial biaxial compression

The post-buckling behavior and the ultimate strength of simply-supported, thin, rectangular, steel plates subjected to partial biaxial compressive loads have been established in this study. The computer-aided analytical technique used accounts for large deflections, elastic-perfectly plastic material behavior, residual stresses and initial out-of-plane deflections. The method of analysis is based on the principle of minimum potential energy and …
