Experimental study of inelastic deformation at the micro scale in cemented granular materials: some recent results Tengattini, Alessandro; Einav, Itai; Viggiani, Gioacchino (CIMNE, 2013)
Open AccessA novel thermomechanical constitutive model for cemented granular materials has been recently introduced. An essential ingredient of the model is the use of measurable and micro-mechanics based internal variables describing ...
