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…

An isogeometric finite element formulation for frictionless contact of Cosserat rods with unconstrained directors
Myung-Jin Choi, Sven Klinkel, Roger A. Sauer
This paper presents an isogeometric finite element formulation for nonlinear beams with impenetrability constraints, based on the kinematics of Cosserat rods with unconstrained dir…
