Abstract: A rock burst can cause a serious disaster. For the mitigation of rock burst-induced disaster, the possibility assessment of a rock burst for an underground excavation is a key undertaking and also a great challenge because ...
OpenMP-Based Parallel Two-Dimensional Discontinuous Deformation Analysis for Large-Scale Simulation
Publisher: ASCE
Abstract: Discontinuous deformation analysis (DDA) has gained wide acceptance in geotechnical engineering. The simulation of large-scale engineering problems using DDA is computationally expensive. Thus, improving the calculation ...
Three-Dimensional Numerical Manifold Method Based on Viscoelastic Constitutive Relation
Publisher: ASCE
Abstract: In order to accurately and efficiently simulate the dynamic processes of coupled phenomena with viscoelastic, continuous and discontinuous deformations, a three-dimensional (3D) numerical manifold method combining Maxwell's ...
Remedies for Distortion and False Volume Expansion Problems with Large Rotation in Discontinuous Deformation Analysis
Publisher: ASCE
Abstract: When simulating large rotation, the false volume expansion and elastic distortion problems of the block occurs severely in the original discontinuous deformation analysis (DDA). In this study, a new displacement formula ...
Optimization of Sustainable Alkali Activated Municipal Solid Waste Incinerator Bottom Ash Materials with High Performance
Publisher: American Society of Civil Engineers
Abstract: In general, municipal solid waste incinerator bottom ash (IBA) is mainly utilized as fillers in nonstructural concrete products due to its low reactivity. In this study, the high-strength alkali-activated materials (AAMs) ...
