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 ...
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. ...
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 ...
