»Injective nonlinear elasticity via penalty terms: analysis and numerics«

I will present some new ideas for nonlinear elasticity with a global injectivity constraint preventing self-interpenetration of the elastic body. Our main focus are penalization terms replacing this injectivity constraint, the Ciarlet-Nečas condition. Among other things, the penalization can be chosen in such a way that self-interpenetration is prevented even at finite value of the penalization parameter, and not just in the limit. Our penalty method provides a working numerical scheme with provable convergence along a subsequence, for models of non-simple materials (i.e., including a term with higher order derivatives). This is joint work with Jan Valdman (UTIA CAS Prague)


Hierzu ergeht herzliche Einladung.
