... and accurate experimental results are given by a series of tests carried out at the Laboratory 3S in Grenoble. For such tests a biaxial apparatus, developed by Desrues (1984) and modified by Charrier et al. (2001), has been employed in plane strain conditions. The results of the tests, carried out...
