More numerical experiments on linear and nonlinear elasticity problems

This presentation describes the contribution of the group at KUN to Work-packages 2 and 3 in the following directions: (1) study of the properties and the behavior of variable versus fixed preconditioners, based on the so-called separate displacement component (SDC) formulation of the linear elasticity problem; (2) solution of problems with nearly incompressible material properties, based on a ...

Model Problems from Nonlinear Elasticity: Partial Regularity Results

Ω |Du| + f(AdjDu) + g(detDu), where u : Ω ⊂ IR → IR, f grows like |AdjDu|p, g grows like |detDu|q and 1 < q < p < 2, is C on an open subset Ω0 of Ω such that meas(Ω \ Ω0) = 0. Such functionals naturally arise from nonlinear elasticity problems. The key point in order to obtain the partial regularity result is to establish an energy estimate of Caccioppoli type, which is based on an appropriate ...
