An isogeometric finite element formulation for boundary and shell viscoelasticity based on a multiplicative surface deformation split
Karsten Paul, Roger A. Sauer
This work presents a numerical formulation to model isotropic viscoelastic material behavior for membranes and thin shells. The surface and the shell theory are formulated within a…
Isogeometric continuity constraints for multi-patch shells governed by fourth-order deformation and phase field models
Karsten Paul, Christopher Zimmermann, Thang X. Duong +1
This work presents numerical techniques to enforce continuity constraints on multi-patch surfaces for three distinct problem classes. The first involves structural analysis of thin…
An adaptive space-time phase field formulation for dynamic fracture of brittle shells based on LR NURBS
Karsten Paul, Christopher Zimmermann, Kranthi K. Mandadapu +3
We present an adaptive space-time phase field formulation for dynamic fracture of brittle shells. Their deformation is characterized by the Kirchhoff-Love thin shell theory using a…
