... stress distributions better than the power law and closer to elastic-plastic solutions for textbook cases such as thick cylinder, beam, etc. This part of the article offers several numerical examples to demonstrate the robustness of the method. Upper and lower bound limit loads are calculated using...

...Sathya Prasad Mangalaramanan Statically admissible stress distributions are necessary to evaluate lower bound limit loads. Over the last three decades, several methods have been postulated to obtain these distributions using iterative elastic finite element analyses. Some of the pioneering...
