Variational Methods for Continuum Models of Granular Materials
Continuum models of granular materials aim to describe their behavior in average sense while exploiting the paradigm of continuum mechanics. For granular materials, however, success of these continuum models is predicated upon how they treat grain interactions and grain kinematics within the formulation.
Continuum Models of Granular Materials
Continuum approaches can be more efficient and desirable for granular mechanics problems that require a macro-scale description involving a large number of grains (>106grains) with varying sizes and bulk and surface characteristics packed in a disordered state. In these cases, an average behavior is sufficient, and it is not necessary to obtain the trajectory of each grain as well as the spatial distributions of deformation energies at the grain-scales. For such problems, the discrete approach may be constrained, not only by its...
