... is fragmented, and many assumptions used in numerical simulations are not properly justified. This is unlike Newtonian fluid flow in fractures where a considerable progress has been made over the last 30 years. Open questions and topics that need further investigation are identified based on the review...

... for plasticity, and 3 for creep. The proposed model is first validated by comparing the triaxial tests of sandstone under different hydrostatic stress and cyclic loading conditions. Then, it is versatile in simulating the time-dependent behavior through a series of multi-staged creep tests. 1 INTRODUCTION...

... of numerical methods have been developed as useful tools to simulate failure and general behaviors of brittle rock fractures. Those methods can be divided into two types, one is microscopic method, such as molecular dynamic (MD) (Holland & Marder, 1998); and the other is mesoscopic approaches, such as FEM...

For the laboratory tests, the deformation properties (expressed by stress-strain curve) and failure process of granite under compression and tension were investigated. In addition, the evolution of dilatancy and time-dependent...

An energy-absorbent support system is recommended for the rehabilitation of the side walls of the cavern. Introduction The construction...

.... To feature of the overlapping ore body, as well as the engineering characteristics of caking ore in Tongkeng Mine, measure was used to induce and break caking ore by blasting roof. Using LSDYNA numerical methods, numerical tests were designed to simulate breaking process of caking ore in different falling...
