Flexural-torsional elasto-plastic buckling analysis of stiffened plates using dynamic relaxation. Part 2: Comparison with test results and other formulations (original) (raw)

This paper presents an in-depth analysis of the flexural-torsional elasto-plastic buckling of stiffened plates, using a dynamic relaxation approach. It focuses on experimental and theoretical research, comparing the derived results with empirical data from various tests conducted on stiffeners used in structural applications such as aircraft and civil engineering. Key findings highlight the importance of accounting for geometrical and material nonlinearities alongside the interaction effects between shell plating and stiffeners, ultimately contributing to the refinement and validation of current design approaches.
