WebSep 3, 2006 · Abstract: We present an extended formulation of a non-linear continuum visco-elastic damage rheology that accounts for non-local damage accumulation, dynamic fracturing, and transition from solid to granular state in the slip zone. Generalizing the standard Hookean strain energy, the model has three additional energy terms: a non …
