Approche multiéchelle des systèmes de tenségrité
Résumé
A specific feature of multicontact problems is the large number of contact or interaction conditions that leads to large scale problems. Several approaches, among them algorithm parallelization, have been designed to tackle the numerical difficulties arising from such problems. This work belongs to these algorithms, using the LATIN (LArge Time INcrement) multiscale approach. As a first step, the case of tensegrity systems is considered as a particular discrete medium.
