• Abstract:
  Many high-rate impact applications in the aerospace industry, such as a fan blade out event, can induce ductile fracture under loading conditions that are difficult to replicate experimentally. Varying temperatures and strain rates can influence fracture behavior, but the primary variable that drives fracture initiation in a ductile material is the state of stress. If numerical models of applications involving ductile fracture at complex stress states are to be trusted, it is necessary to develop novel fracture testing techniques that can be used to calibrate fracture criteria in finite element material models.
