Journal ArticleDOI
Applying modified discontinuous deformation analysis to assess the dynamic response of sites containing discontinuities
TL;DR: In this paper, a modified Discontinuous Deformation Analysis (DDA) with the ability to study discontinuity behaviors was proposed by incorporating a seismic input method based on a viscous boundary and the free-field theory.
Journal ArticleDOI
Parallel computing of three-dimensional discontinuous deformation analysis based on OpenMP
Xinyan Peng,Guangqi Chen,Pengcheng Yu,Yingbin Zhang,Yingbin Zhang,Longxiao Guo,Cungen Wang,Cungen Wang,Xiao Cheng,Xiao Cheng,Hui Niu +10 more
TL;DR: This paper proposes implementing the parallel block Jacobi (BJ) and preconditioned conjugate gradient (PCG) iterative solvers into the original 3D-DDA based on OpenMP to accelerate the equation-solving process.
Journal ArticleDOI
Development of a Coupled DDA–SPH Method and its Application to Dynamic Simulation of Landslides Involving Solid–Fluid Interaction
TL;DR: In this article, a coupled Discontinuous Deformation Analysis (DDA) and Particle Hydrodynamics (SPH) method is proposed to simulate the landslide failure process.
Journal ArticleDOI
Evaluation of impact force of rock landslides acting on structures using discontinuous deformation analysis
Pengcheng Yu,Pengcheng Yu,Yingbin Zhang,Yingbin Zhang,Xinyan Peng,Jinmei Wang,Guangqi Chen,John X. Zhao +7 more
TL;DR: In this paper, an impact force model for the contact force on the given boundary, rather than the resultant force at the center of gravity is presented and incorporated into Discontinuous Deformation Analysis (DDA).
Journal ArticleDOI
CPU-accelerated explicit discontinuous deformation analysis and its application to landslide analysis
TL;DR: The explicit DDA that uses an explicit time integration procedure and an explicit calculation of interaction forces between blocks is proposed to overcome the limitations of conventional implicit DDA in simulating large-scale problems.
