BESLE is the first available parallel open-source code to analyse mechanical behaviour of heterogeneous materials using boundary element method (BEM) in 3D and both an elastostatic elastodynamic setting. Unlike all other codes that are presently available, software presented here capable simulating isotropic anisotropic comprised single or multiple domains. Furthermore, user-interface has been ...

Toupin's version of the Saint-Venant principle in linear elasticity is generalized to the case of linear elasticity with mierostructure. That is, it is shown that, for a straight prismatic bar made of an isotropic linear elastic material with rnicrostructure and loaded by a self-equilibrated force system at one end only, the strain energy stored in the portion of the bar which is beyond a dista...

SUMMARY Using well{known concepts from the scalar case (cf. Kor94]) we derive globally convergent multigrid methods for the discretized Signorini problem in linear elasticity. Special care has to be taken in case of varying normal directions. The algorithm can be implemented as a multigrid V{cycle with optimal complexity. In numerical experiments we observed similar convergence rates as for lin...
