Diffuse and localized deformation of a porous Vosges sandstone in true triaxial conditions
This work presents an experimental study on the diffuse and localized deformation mechanisms of a high porosity (20%) Vosges sandstone (Eastern Grabbers France) subjected to different stress paths in the deviatoric plane.The experimental campaign was performed using a high pressure true triaxial apparatus (TTA) in which the three principal stresses
