Adaptive virtual element method for large-strain phase-field fracture. (English) Zbl 1504.74081
Aldakheel, Fadi (ed.) et al., Current trends and open problems in computational mechanics. Cham: Springer. 195-206 (2022).
Summary: In this contribution, the phase-field (PF) approach to brittle fracture is extended to adaptively refined meshes at finite strains. Such mesh refinement produces regular structured elements with hanging nodes at edges. These hanging nodes can be included to the mesh by employing the Virtual Element Method (VEM). The model performance is demonstrated by two representative numerical examples.
