Sensitivity analysis for problems exhibiting geometric nonlinearities and follower loads using the complex-variable finite element method

This study presents an enhanced approach for conducting sensitivity analysis of nonlinear problems involving a combination of geometric nonlinearities and follower loads, particularly those involving displacement-dependent forces. The method utilizes the complex-variable finite element method (ZFEM)...
