Paper presented at the ISRM 2nd International Conference on Rock Dynamics, May 18–19, 2016
Paper Number: ISRM-ROCDYN-2016-30
... strength are obtained by the difference of the longitudinal stress and lateral stress. Results suggest that rock materials are deforming in the inelastic manner and Hugoniot Elastic Limit (HEL) is deduced. Experimental results are compared and contrasted to the existing data for other geological materials...
