If you want to apply the Johnson Cook strength and failure model from Explicit Dynamics system directly to WB LS-DYNA system, you need to insert a keyword snippet in the LS-DYNA system and then add the keyword *Mat_Add_Erosion to account for material failure. Make sure the material ID is consistent with the material that has Johnson-Cook failure.nIn ANSYS 2021R1, a collection of selected LS-DYNA material models is added into Engineering Data for user to use. See the picture below. You may use this module to define the Johnson-Cook materials, for example, *Mat_Simplified_Johnson_Cook, in LS-DYNA systems to simulate material failure.nnn
