    Conference report
    Open Access
    In this paper, unstable fracture propagation obtained in a in-house performed experimentalWedge Splitting Test (WST) is simulated by means of the FEM and fracture- based zero-thickness interface elements. In order to obtain ...
  • Coupled H-M fracture interaction using FEM with zero-thickness interface elements
