The Formability of sheet metals Previous posts Materials Matters- “The known unknowns”  and “Material plasticity visualized” covered the general aspects, common terminology, and formulation of the plastic properties in sheet metal forming problems. Accurate definition of flow curves, kinematic hardening…
