Forming limit and fracture mechanism of ferritic stainless steel sheets

▶ Forming limit curves of two ferritic stainless steel sheets were well predicted. ▶ Failure occurs by necking in uniaxial and plane strain tension for both materials. ▶ Failure occurs by shearing in balanced biaxial tension for both materials. ▶ Strain rate sensitivity does not affect the limit strains a lot for both materials. ▶ Strain rate sensitivity likely influences the failure mode for both materials.
