failure crterion for powdered metal
failure crterion for powdered metal
(OP)
I am designing a small powdered metal part for the automotive market and I am not sure what failure criteria I should use for the FEA. The part will see a significant bolt up load but very little dynamic load. Elongation at fracture of this material is about 4%. Should I consider it a failure when the max principle stress exceeds the yield strength of the material (i.e. max principle stress theory)? This seems appropriate since the material is brittle but I don't have much experience with powdered metal.

what is the powder alloy you are processing and the part being made? Perhaps soon others would join in,once enough details are available.
