Nonlinear criteria and the influence of the average principal stress on rocks destruction
(National Mining University, 2018-12-30)
Purpose. Consider possible series methods of Mohr-Coulomb nonlinear criterion that takes into account stresses in the plane of fracture. Investigate the influence of the average principal stress on rocks destruction when ...
Simulation of sample testing under compression with the help of finite-element model of rocks being broken
(National Mining University, 2018-09-30)
Purpose of the paper is to develop mathematical model describing nature of argillous and salt samples under compression and to make available microdefects using finite-element method. Methods. To simulate behaviour of ...
