Incorporating rolling resistance and contact anisotropy in micromechanical models of granular media

摘要: Recent findings from non-invasive experiments have shown that rolling resistance and contact anisotropy a significant influence on the bulk behaviour of granular media. To date, however, there has been no generalised continuum model accounts for both these factors. In this paper, we propose method by which may be introduced in micropolar capture key microstructures like shear bands, homogenisation procedure scale particle its local void space is developed.
