How to define Contact for pourous plastic material in Abaqus/Explicit?

11 November 2017 0 7K Report

I'm simulating the metal deep drawing for porous ductile metal by Abaqus/Explicit and It get a problem.

" Some elements underlying deformable surface ASSEMBLY_BLANKBOTSURF are referenced by a *CONTACT PAIR option. In addition these elements have material properties that allow the elements to fail. For elements that can fail, contact should be defined using the *CONTACT option. A element set named "WarnElemFailElemInContact" containing these elements is created to help the user locate the elements"
