摘要

The stress estimated by the Equivalent Inclusion Method is compared with the one converted from the contact forces between the granules in the equivalent DEM simulation to capture the feature of the equilibrium within the granular assemblage under shearing. The applicability of the stress inversion strategy by the Equivalent Inclusion Method is examined through the comparison.
