A low order, torsion deformable spatial beam element based on the absolute nodal coordinate formulation and Bishop frame
Mehran Ebrahimi, Adrian Butscher, Hyunmin Cheong
Heretofore, the Serret-Frenet frame has been the ubiquitous choice for analyzing the elastic deformations of beam elements. It is well known that this frame is undefined at the inf…

Optimal design of frame structures with mixed categorical and continuous design variables using the Gumbel-Softmax method
Mehran Ebrahimi, Hyunmin Cheong, Pradeep Kumar Jayaraman +1
In optimizing real-world structures, due to fabrication or budgetary restraints, the design variables may be restricted to a set of standard engineering choices. Such variables, co…
