Abstract

As resourceful stress states, high strain rates, and large plastic deformation were involved, the Taylor test can be used to identify the most suitable fracture criterions for high velocity impact problems. A systematic evaluation is carried out for the maximum principal stress, the maximum principal strain, equivalent plastic strain and Johnson-Cook fracture models by numerical simulations. The applicability of the ductile fracture models are discussed, finally.
