Is this the specific difference?&lt;br&gt;Also, the Johnson-Cook fracture model is a model in which fracture is determined when accumulated strain exceeds a certain value, but I feel that this is inappropriate to apply to materials such as metals that fracture at a certain value, and that the model is more suitable for materials such as composites in which strain accumulates over a long period of time.
