... Abstract Some projects, such as application of energy piles, underground storage of nuclear waste, geothermal development and laying of heat pipes, are necessary to consider the effect of temperature on the mechanical properties of clay. Test results have shown that clay may show two different...

... Abstract Seismic load is a type of dynamic load that can easily induce the failure of the foundation slope. Using the continuum-based discrete element method in continuum mechanics, herein, the rupture degree and permanent displacement are defined and their evaluation steps are proposed...

... or physical laws based on damage and fracture mechanics but the integration from the characterization to the modeling is not firmly established. The authors developed continuum numerical model with the subcritical crack growth test and acquisition of parameters from the laboratory test. The developed model...

... Abstract An important aspect of the behavior of joints in rock masses is damage and degradation of mechanical properties due to progressive fracturing of the rock bridges or cemented materials existing in the joint. The damage can occur in both normal and shear modes. In this work a coupled...

...). Introduction In recent years, Discrete Element Method (DEM) is extensively used to model brittle materials [1,2]. Jing and Stephansson [3] have recently provided fundamentals of DEM and its application in rock mechanics. One use of DEM is to represent rock-type material as a dense packing of non-uniform-sized...
