Observational analysis captures behavior of granular matter, indicating potential for enhancing collapse and avalanche modeling.
In this contribution, we discuss the ability of elasto-viscoplastic constitutive models in capturing the diverse behavior of granular media as both solids and liquids. In particular, we showcase the recently developed MCC-μ(I)-rheology [1], which combines the Modified Cam-Clay (MCC) model for granular solids with the μ(I)-rheology for granular liquids, creating a “best-of-both-worlds” model for describing granular solids and liquids in a single framework. This model is demonstrated on various problems, including granular collapse tests as well as full-scale avalanche modeling.
