An enriched phase-field method for the efficient simulation of fracture processes

Abstract The efficient simulation of complex fracture processes is still a challenging task. In this contribution, an enriched phase-field method for the 2D presented. It has potential to drastically reduce computational cost compared classical (PFM). based on combination approach with ansatz transformation and enrichment technique displacement field as it used in extended finite element (XFEM) or generalised (GFEM). This allows application significantly coarser meshes than possible PFM while obtaining accurate solutions. contrast XFEM / GFEM, presented does not require level set techniques explicit representations crack geometries, considerably simplifying initiation, propagation, coalescence. efficiency accuracy new shown simulations.
