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 BorkoviÄ, 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…
Efficient snap-to-contact computations for van der Waals interacting fibers
Aleksandar BorkoviÄ, Michael H. Gfrerer, Roger A. Sauer +1
We consider van der Waals interactions between in-plane fibers, where the computational model employs the Lennard-Jones potential and the coarse-grained approach. The involved 6D i…
On analytical integration of interaction potentials between cylindrical and rectangular bodies with a focus on van der Waals attraction
Aleksandar BorkoviÄ, Michael H. Gferer, Roger A. Sauer
The paper deals with the analytical integration of interaction potentials between specific geometries such as disks, cylinders, rectangles, and rectangular prisms. Interaction pote…
