DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NSCM/98/">Se
 lf-contact for inertial problems in continuum mechanics</a>\nby Malte Kamp
 schulte (Faculty of Mathematics and Physics\, Charles University) as part 
 of Nečas Seminar on Continuum Mechanics\n\nLecture held in Room K3\,  Fac
 ulty of Mathematics and Physics\, Charles University\, Sokolovská 83  Pra
 gue 8..\n\nAbstract\nThere are many theories about elastic collisions of s
 olids and the resulting inertial evolution. What unifies most of them is t
 hat they involve some phenomenological assumption. The aim of this talk is
  to present a recent result which shows that for the self-collision of ela
 stic bulk solids\, it is in fact sufficient to consider matter non-interpe
 netration. Based only on this\, we are able to derive existence of weak so
 lutions including contact with obstacles and self-contact for arbitrary la
 rge times and for large deformations. Additionally we are able to precisel
 y characterize the contact forces as a vector-valued measure. This is base
 d on joint works with A. Češík\, and  G. Gravina.\n
