Scope of the Symposium

The investigation of multiscale problems in multibody system contacts is a most interesting and timely topic which is subject of intensive research for more than one decade. While many questions have been answered and the mechanically sound description and simulation is increasingly applied in practical engineering problems, an IUTAM Symposium fasciliates discussioins between researchers active in the field and enables us to review the state-of-the-art and to identify for the years to come the hot topics which require further efforts.

It wil be especially useful to bring together scientists from closely related but traditionally distinct fields such as multibody system contact, molecular dynamics, finite element contact, collision detection or the mathematics of unilateral contact. It is observed that the once clear boundaries between these fields blur and an exchange of ideas will accelerate the development with mutual benefits.

Multiscale problems occur very naturally in contact mechanics. Typically the contact forces and stresses are very high and they are transmitted within a very short period of time. This leads to questions, e.g. how the slow rigid body motion and the fast motion changes can be considered simultaneously or how interface effects couple to wave propagation and the large-scale motion.
