I am interested in using beam element to do a nonlinear static analysis (may need to a dynamic analysis in the future), but have trouble to understand some of the key features of beam element in abaqus or ansys. My goal is to find a beam element (preferably general beam section) with a defined stress resultant yield surface (e.g., P-M-M yield surface). If possible, could also account warping degree of freedom.
