Thank you for your reply.
When I run the program with only the strength model set and without the destruction model set, a phenomenon resembling destruction occurs. What does this mean?
I understand that the Johnson-Cook strength model determines destruction by stress, while the Johnson-Cook destruction model reproduces destruction by strain. Is this correct?
