Micro Abstract:
Firstly, the isogeometric Kirchhoff-Love (KL) shell model is combined with phase-field fracture description. Secondly, the KL shell formulation is applied to elasto-plastic models at large deformations. Thirdly, this elasto-plastic KL shell formulation is coupled with phase-field ductile fracture model. A careful investigation on various numerical and benchmark examples and detailed comparisons with 3D solid simulations and with solutions from the literature are carried out.
