By Frédéric Lebon, Michel Raous, Iulian Rosu (auth.), Peter Wriggers, Udo Nackenhorst (eds.)

This publication includes the lawsuits of the IUTAM Symposium held in Hanover, Germany, in November 2006. assurance contains new mathematical ideas like multi-level ways, new discretization options just like the mortar-method, complex purposes of unilateral touch to masonry buildings, decohesion research and tractive rolling of tires.

It offers a very good assessment of contemporary innovations and cutting-edge discretizations schemes utilized in touch mechanics. insurance will stimulate destiny collaboration in technological know-how relating to computational touch mechanics and within the association of minisymposia and workshops within the quarter touch mechanics.

The IUTAM Symposium introduced jointly scientists who paintings at the frontier of analysis in computational touch mechanics or in heavily similar matters. on the assembly, 37 scientists offered their most modern findings within the quarter of discretization ideas for touch, algorithms and engaging numerical simulations of touch difficulties.

P∈S For general inf-sup stable pairings, the contact conditions results in a segment to segment approach, where the inequality constraints can only be resolved by some global optimization procedure on the contact boundary. This is not the case, if we work with a locally defined biorthogonal basis of the LM space. Then the segment to segment approach is algebraically equivalent to a node to segment approach, and the inequality constraints decouple. Additionally, we can rewrite by a local preprocess a two body problem into a one body problem and the same solver can be applied.
