MS4: Advanced modeling of contact interfaces in forming

Animators: P. Montmitonnet (CEMEF,Fr)

Objectives: Although constant progress has been made in the treatment of contact non-linearity, it remains a major source of trouble in numerical simulation of manufacturing processes. Contact and interface behavior is indeed gaining more importance as new processes such as FSW or additive manufacturing emerge, putting more emphasis and stronger pressure on contact algorithms due to very large sliding lengths or plastic deformation. With very large amounts of interfaces and of contact surface evolution, there is a need for faster yet accurate methods. More complex physics occurs there as well, under "extreme conditions" for which new, accurate models must be implemented and coupled. This reinforces the trend towards a sharper description of contact and interfaces physics (wear, friction, adhesion or debonding) for more precise predictions in industrial applications.

The Mini-Symposium "Advanced modeling of contact and interfaces in forming" is calling for papers describing scientific work on novel contact algorithms and numerical implementation of advanced models of interfaces and contact. All numerical methods are considered, applications to all processes and materials are welcome. The following list of keywords / topics is by far non-exhaustive:

modelling of contact under large deformation
numerical modelling of wear
advanced friction model implementation
coupling lubrication models with metal forming simulations
friction instabilities, incipient sliding in metal forming simulation
joining and adhesive bonding processes: modelling the creation of physical bonds
debonding and delamination
