... the analyses possible. Small elements that contain only a few joints or none at all are allowed in the NRVE approach, so mesh gradation can be made adequate in regions of high stress concentration. Two-dimensional simulations of open pit mining sequences result in rounded, stair-step curves...

... and subjected to the action of a step tensile pulse applied at opposite dges of the plate. Several finite element discretizations are used to examine the mesh size effect. Comparisons between calculated results based on local and nonlocal formulations are made and nonlocal effects are discussed. 1 INTRODUCTION...

... using the concept of Shi's manifold method, which separates mathematical mesh from physical mesh. Solid blocks are formulated mainly according to Shi's discontinuous deformation analysis. The mathematical mesh for the fluid domain is fixed three-noded finite elements, and its physical domain...

... ABSTRACT ABSTRACT: Reinforced shotcrete maintains its functionality and sustains only minor damage when exposed to peak particle velocities of 1.5 to 2 m/s (60 to 80 in/s) due to nearby blasting. Mesh reinforced shotcrete performs better than steel fibre reinforced shotcrete under very severe...
