Numerical experiments concerning long-term deformation of rock samples
(National Mining University, 2019-12-30)Purpose is to develop modeling methods of long-term rock sample deformation and failure under various loading conditions with the help of finite-element method of failure rock modeling (DESTROCK-FE). Methods. DESTROCK-FE ... -
Resonance in rock mass as the key reason of geodynamic phenomena
(National Mining University, 2019-06-30)Purpose is to develop deformation criterion or predecessors of geodynamic phenomena within rock mass relying upon the systemized experimental data concerning rock behaviour in a volumetric field of compressive stress. Methods. ... -
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 ... -
Studying a crack initiation in terms of elastic oscillations in stress strain rock mass
(National Mining University, 2016-06-30)Purpose. Deriving the criterion of a crack (joint) initiating under simultaneous effect of the rock stress state and elastic oscillations generated by an external source is the research purpose. Determining the quantitative ...
