Displacement‐Correlated XFEM for Simulating Brittle Fracture [PDF]
Computer Graphics Forum, 2020 AbstractWe present a remeshing‐free brittle fracture simulation method under the assumption of quasi‐static linear elastic fracture mechanics (LEFM). To achieve this, we devise two algorithms. First, we develop an approximate volumetric simulation, based on the extended Finite Element Method (XFEM), to initialize and propagate Lagrangian crack‐fronts ...
