This Minisyposium is devoted to recent developments on the various aspects of contact mechanics: • Interface behaviour: unilateral contact, friction, adhesion, CZM, viscosity, fretting, wear, peeling, rolling contact, contact in biomechanics, fluid flow in contact interface. • Computational models: multilevel approaches (molecular and nano-micro-macro models), multi-physics (thermo-piezo- …), coupled multi-field formulations, fractal surface characterization, homogenization, bi-potential. • Computational methods: fast solvers, multigrid, isogeometric analysis, NURBS, virtual elements. • Dynamics of structures and of rigid bodies, instabilities. • Discretization methods for overlapping immersed and embedded meshes. • Mathematical progresses. • Industrial applications involving interface and contact conditions.
