Micro Abstract:
To increase the computational efficiency of phase field models of ductile fracture, we have developed an isogeometric framework for adaptive local mesh refinement. This includes appropriate marking criteria to select elements for refinement, the creation of the locally refined basis and a projection of the nodal displacements and internal variables. We provide and analyze marking criteria and projection methods and compare their numerical applicability in several numerical examples.
