Failure criteria?

(OP)
Hi, what is the diference whether we set up fail stress, (fail strian) or not?
When I plot data from field output, I didn't see the differrence?  

RE: Failure criteria?

Dear
i am working with DEBOND two surfaces, my file get this kind of massage: "THE SLAVE-MASTER PAIR ASSEMBLY_DB2 ASSEMBLY_DB1 SPECIFIED ON *DEBOND HAS NOT BEEN DEFINED. THIS MAY BE DUE TO NONEXISTENT SLAVE OR MASTER  SURFACE, OR DUE TO ERRORS WHEN PROCESSING THE *CONTACT PAIR KEYWORD". Althought i have already defined it in CONTACT PAIR and again in INITIAL CONDITIONS. Please help me how to solve this problem.

Thanks
