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…
