Validating the ability of the discontinuous deformation analysis method to model normal P‐wave propagation across rock fractures

Abstract: Summary The effects of fractures on wave propagation problems are increasingly abstracting the attention of scholars and engineers in rock engineering field. This study aims to fully validate the ability of discontinuous deformation analysis (DDA) to model normal P‐wave propagation across rock fractures. The effects of a single fracture and multiple parallel fractures are all tested. The results indicate that DDA can accurately reflect the fracture effects, including the fractures stiffness, the fracture spaci… Show more

“…The second approach is numerical simulation. The discontinuum‐based methods, such as the discrete element method, the discontinuous deformation analysis method, and the numerical manifold method, can simulate the failure process of the rock blocks under seismic action 18–23 . The third approach is the Newmark sliding block method 24 .…”

“…2 As an implicit and displacement-based method, DDA have been successfully implemented on both static and dynamic problems in rock engineering. 3 In the past decades, many improvements have been made on the discontinuous computation framework for the analyses of rock slides, 4-7 tunnels, 8,9 seismic site response, 10,11 rock fragmentation, [12][13][14] rock dynamics, [15][16][17][18] hydraulic fracturing, [19][20][21][22][23] and thermo-hydro-mechanical problems. [24][25][26] Meanwhile, the implementation of three-dimensional DDA has gained popularity in various rock engineering problems.…”
