Course Objectives | |
Provide the scientific and technological bases about the most common forming processes based on plastic deformation of metallic materials. Obtain a precise understanding of the metal sheets forming by deep drawing. Learn how to establish and use a forming limit diagram in order to predict the formability of metal parts by stamping. |
|
Syllabus | |
Reminder of elastoplasticity: strain hardening curve, common stress-strain material laws and von Mises criterion. Study of metal sheets anisotropy: origins of the plastic anisotropy, Lankford coefficient and modification of yield criterion. Study of metal forming: formability caracterisation tests (Bulge, Erichsen, Swift ...), forming limit diagrams. Industrial techniques of metal forming by plastic deformation: presentation of different industrial processes (rolling, wire drawing, forging, stamping...), initiation to basic calculations for rolling and wire drawing. |
