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…

An objective isogeometric mixed finite element formulation for nonlinear elastodynamic beams with incompatible warping strains
Myung-Jin Choi, Sven Klinkel, Simon Klarmann +1
We present a stable mixed isogeometric finite element formulation for geometrically and materially nonlinear beams in transient elastodynamics, where a Cosserat beam formulation wi…
