Математическое моделирование напряженно-деформированного состояния связного сыпучего материала в конической области

Abstract

A model of the stress-strain state of loose material is considered at present paper. The material has a microstructure and properties of flowability, plasticity, and adhesion. The multiparameter nature of the proposed model allows evaluating the kinematics and stresses in the loose material under the gravity in a cone-shaped container. The stress state depending on the rolling friction coefficient and the cone angle of the region is obtained. The dependence of the displacement velocity on the cone angle of the region is determined.
