TOPICS:

•        Fundamentals of tribology

•        Introduction to tribology in sheet metal forming

–       Contact conditions, surface topology and friction in deep drawing processes; underlying friction mechanisms in deep drawing processes: adhesion, ploughing, lubrication regimes; classical friction tests.

–       Flattening due to normal loading and sliding; surface roughness evolution due to sub-surface (substrate) plastic deformation

–       Wear mode diagram; single asperity ploughing model; slip-line field theory

•        Introduction to metal plasticity

–       Stress-strain behavior (including temperature effect); yield functions; strain hardening postulates; plastic flow rules; large deformations; forming limit diagrams

•        Advanced friction models in sheet metal forming and implementation in FEM  

–       Multi-scale friction model; evolution of friction during metal forming (position dependent);

–       Contact algorithms in FEM

–       FE implementation of advanced friction model (in full-scale simulations)

•        Tribology Lab tour
