Cohesive granular materials are known for their pressure-dependent strain softening behavior that is intimately linked to their microstructure and grain interactions. To understand the relationship of mechanical properties, composition and structure of these materials, we have been developing continuum theories utilizing higher displacement gradients and micromechanics [1-5]. In this presentation, we will first describe the second gradient continuum theory using the principal of virtual work to establish the governing equations and the boundary conditions.
