Mechanical treatment at interface surfaces is an important aspect to many analyses. These interfaces may be physical in form such as contact/impact or fracture/crack interfaces or numerical in form such as immersed boundary/embedded or domain decomposition. Although a lot of progress has been achieved, there are still many outstanding challenges, and the field has diversified in many directions. This session is devoted to recent developments on the various aspects of interface mechanics:
  • Computational treatment of unilateral contact, friction, adhesion, fretting etc.
  • Discretization methods for overlapping immersed and embedded meshes.
  • Optimization, Reduced Order Modeling and Machine Learning applied to interface problems.
  • Multilevel approaches (molecular and nano-micro-macro models) for interfaces.
  • Multiphysics modeling (e.g., piezo, thermal, fluids) involving interface surfaces.
  • Computational methods: fast solvers, multigrid, isogeometric analysis, NURBS, virtual elements, etc.
  • Dynamics of structures and rigid bodies in unilateral contact or interface coupling.
  • Industrial applications involving interface modeling.
Besides presentations of new results and new contributions to the understanding of interface mechanics and its numerical treatment, this session will provide an opportunity to discuss and exchange ideas on the various topics related to the field.
