<p>In this paper we examine if it is possible to determine the mechanical REV from (Representative Elementary Volume) analyses carried out on geometrical parameters, which don't require mesh making.</p>

<p>In this paper detailed engineering geological characterization and performance observations were carried out at the site of the Kallat tunnel in the north east of Iran. Numerical modeling studies (FEM and DEM) based on mapped field data and laboratory data, ...

<p>This paper applies numerical limit analyses to evaluate the ultimate bearing capacity of a surface footing resting on a rock mass whose strength can be described by the generalized Hoek-Brown failure criterion.</p>

<p>In numerical analyses involving multiple geological materials, predicted stress distributions, deformation patterns, and failure mechanisms depend on the ratios of the Young's moduli for the different materials, a detailed often overlooked. Using two simple ...

This paper describes a method that allows direct use of the Generalized Hoek-Brown criterion in Finite Element (FE) Shear Strength Reduction (SSR) analysis of rock slopes. It describes the generation of shear envelopes for the criterion, lowering of the shear ...

<p>These lecture notes introduces the field of rock slope stability analysis and the purpose such analyses serve in the investigation of potential slope failure mechanisms. Advancements in and the evolution of computer based slope analysis techniques are discoussed, ...

The calculations reported here illustrate that simulations of crack branching with cohesive surfaces between all elements are not well posed in the sense that the results continually change with mesh refinement. Introducing an additional length scale into ...
