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…
Reduced integration with scaled boundary parametrization for virtual elements at finite strains
Njomza Pacolli, Bjorn Sauren, Jannick Kehls +3
This contribution presents an alternative stabilization technique for the virtual element method (VEM) based on reduced integration combined with a scaled boundary parametrization.…
An enhanced single Gaussian point continuum finite element formulation using automatic differentiation
Njomza Pacolli, Ahmad Awad, Jannick Kehls +4
This contribution presents an improved low-order 3D finite element formulation with hourglass stabilization using automatic differentiation (AD). Here, the former Q1STc formulation…
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…
A selectively reduced degree basis for efficient mixed nonlinear isogeometric beam formulations with extensible directors
Myung-Jin Choi, Roger A. Sauer, Sven Klinkel
The effect of higher order continuity in the solution field by using NURBS basis function in isogeometric analysis (IGA) is investigated for an efficient mixed finite element formu…
