摘要
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.
