A comparative study between DEM and micropolar hypoplasticity

J Lin, W Wu - Powder Technology, 2016 - Elsevier
Both discrete-element-method (DEM) and continuum method are used to model element
tests of granular materials, including biaxial tests and simple shear tests. For the continuum …

Asymmetry of the stress tenor in granular materials

J Lin, W Wu - Powder Technology, 2016 - Elsevier
One of the basic assumptions of the micropolar theory is that the stress tensor is not
symmetric. In this paper, asymmetry of the stress tensor is studied with discrete element …
