...Richard Regueiro; Zheng Duan; Beichuan Yan Purpose – The purpose of this paper is to develop a concurrent multiscale computational method for granular materials in the quasi-static loading regime. Design/methodology/approach – Overlapped-coupling between a micropolar linear elastic one...

... in Cosserat continuum modeling of granular materials. Design/methodology/approach – Based on a Cosserat continuum extension of a hypoplastic model for granular media, interpretation of additional parameters are sought through analysis of simple one-dimensional shear. Governing equations are obtained...
