04 September & 05 September at the University of Twente the ASPECT Course on “Fundamentals of Tribology in Sheet Metal Forming”. Implementation of advanced friction model in sheet metal forming simulations.

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

  • Workshop: Simulating cold stamping processes using the advanced friction model
