The present work is devoted to the simulation of stress wave propagation through fractured
elastic media, such as rock mass, by using the numerical manifold method (NMM). A single …

This paper demonstrates and evaluates an integrated system coupling 3-dimensional
binocular photogrammetry and discontinuous deformation analysis (DDA) for stability …

This paper presents an investigation of wave propagation through microfractured rock mass.
The effects of microfracture on wave propagation were observed by a series of scanning …

As the weak structure and main seepage channel of rock mass, the discrete fracture network
(DFN) has a significant influence on the physical and mechanical properties of rock mass. In …

One of the important pre-processing stages in the analysis of jointed rock masses is the
identification of rock blocks from discontinuities in the field. In 3D, the identification of …

Numerical manifold method (NMM) has shown its ability to solve continuous and
discontinuous deformation problems in a unified framework. However, due to the complexity …

We present a reduced-dimensional proper orthogonal decomposition (POD) solver to
accelerate discrete element method (DEM) simulations of the granular mixing problem. We …

Abstract Numerical Manifold Method (NMM) has gained widespread application in
engineering practice due to its capacity to effectively address both continuous and …

This paper proposes a new method using centroid sliding pyramid (CSP) to identify the
removability and stability of fractured hard rock in tunnel and slope engineering. The new …

Identification of three-dimensional rock blocks of rock masses is a key technique in rock
mechanics and rock engineering. The boundary representation (BR) approach could identify …
