The regularity of solutions to the elasto-plastic problem and to variational problems of fast growth

Por Arrigo Cellina (Università di Milano-Bicocca).

Abstract: We consider the problem of the higher differentiability of solutions to some variational problems, characterized by the fast growth of the Lagrangian with respect to the variable gradient. In particular, the case of the elasto-plastic problem, where the Lagrangian is an extended-valued function, will be discussed.

Topological derivative for two-scale topology optimization

Àlex Ferrer
CIMNE - Universitat Politècnica de Catalunya

Abstract: The aim of the talk is to address multiscale topology optimization problems. For this purpose, the concept of topological derivative in conjunction with the computational homogenization method will be considered and the following techniques will be presented:
