A variable-offset joint formulation for beams with arbitrary cross-sections using a null space method
Myung-Jin Choi, Roger A. Sauer, Simon Klarmann +1
In this paper, we present a variational formulation of local configurational constraints that couple multiple beams with arbitrarily shaped cross-sections. Since this formulation r…

A computational model for short-range van der Waals interactions between beams and shells
Aleksandar Borković, Michael H. Gfrerer, Roger A. Sauer
We consider potential-based interactions between beams (or fibers) and shells (or membranes) using a coarse-grained approach with focus on van der Waals attraction and steric repul…
