FEM Implementation of Micropolar Hypoplastic Model

Lin, J. / Wu, W.

A constitutive model based on hypoplasticity and micropolar continuum is developed by complex tensor formulations. The new model is simpler than any existing micropolar models. A characteristic length is the only additional material parameter. This model is implemented into ABAQUS and solved by finite element method (FEM). The simulation result of a simple shear test is compared with results of discrete element method (DEM). The comparison shows that the rotations of particles can be fairly well predicted with the micropolar hypoplastic model.
