Abstract To identify mechanical properties in heterogeneous materials, the local stress fields have to be estimated. The recent developments in imaging techniques allow reaching precise and spatially dense kinematic fields (e.g. displacement, strain

Publikováno v: AIP Conference Proceedings.

We propose a 2D study of jamming at the outlet of a silo in the metastable state by means of the nonsmooth contact dynamics method. The jamming problem in this geometry can be mapped into the avalanche problem on a granular slope. In this analogy, th

International audience; Within the framework of finite deformations and using an approach to the kinematics of contact due to A. Curnier, Q.C. He and J.J. Téléga, we propose a spatial thermodynamic formulation for the problem coupling unilateral co
