“…A study by Yang et al [31] showed that the deletion of dead ends would induce incorrect results in determining elastic parameters of fractured rock masses, especially when the fracture spacing is close to or larger than the trace length. They also developed a FEM mesh-generating technique to avoid these problems.…”

“…Ivars et al [26] simulated the mechanical behavior of jointed rock masses using synthetic rock mass (SRM) modeling and obtained predictions of rock mass scale effects, anisotropy, pre-peak and post-peak properties. For applications of FEM modeling, one major difficulty encountered is the mesh generation for finite element computation of a high density of fractures [22,31]. Pouya and Ghoreychi [22] developed a mesh-generating tool for a rock mass with high fracture density, and studied the mechanical behavior of rock masses using FEM modeling by assuming linear elasticity and Mohr-Coulomb strength criteria for both intact rock and fractures.…”

Yang et al [31] proposed a different mesh-generating technique and studied the REV and elastic compliance tensor based on linear elastic models of both intact rock and fractures. The influence of fracture dead ends on equivalent strain was evaluated and found to be significant when the fracture spacing is close to the fracture length.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
