H-Adaptive Updated Lagrangian Approach for Large-Deformation Analysis of Slope Failure
Publisher: American Society of Civil Engineers
Abstract: This paper presents a novel approach to improving our understanding of complicated slope failure mechanisms that can occur in strain-softening material as well as to evaluating the accompanying postfailure deformation of ...
Modification of SANISAND-MSf Model for Simulation of Undrained Cyclic Shearing under Nonzero Mean Shear Stress
Publisher: American Society of Civil Engineers
Abstract: Adequate simulation of undrained cyclic shearing of sands subjected to nonzero mean shear stresses is crucial for understanding complex behaviors associated with seismic liquefaction. This study presents the modification ...
Simple Yield Surface Expressions Appropriate for Soil Plasticity
Publisher: American Society of Civil Engineers
Abstract: The objective of this paper is to present a number of simple, practical, and useful analytical expressions of a yield surface for geomaterials. In classical plasticity, the analytical expression of a yield surface defines ...
Effect of Anisotropic Consolidation on Cyclic Liquefaction Resistance of Granular Materials via 3D-DEM Modeling
Publisher: ASCE
Abstract: The influence of anisotropic consolidation on the cyclic liquefaction resistance of granular materials is explored using 3D discrete element method simulations. In this study, the term anisotropic consolidation was defined ...
Application of an Anisotropic Constitutive Model for Structured Clay to Seismic Slope Stability
Publisher: American Society of Civil Engineers
Abstract: The anisotropic nature of response and degradation of shear strength from the undisturbed condition to the remolded state are two fundamental and challenging aspects of response in some clay deposits. This paper presents ...
Bearing Capacity of Shallow Foundations in Unsaturated Soil Considering Hydraulic Hysteresis and Three Drainage Conditions
Publisher: American Society of Civil Engineers
Simplified Mapping Rule for Bounding Surface Simulation of Complex Loading Paths in Granular Materials
Publisher: American Society of Civil Engineers
Abstract: This paper presents a bounding surface plasticity model that can be used to simulate complex monotonic and cyclic loading paths. A new mapping rule that only uses the last stress reversal point is introduced to describe ...
Numerical Modeling of Consolidation of Unsaturated Soils Considering Hydraulic Hysteresis
Publisher: American Society of Civil Engineers
Abstract: The consolidation of soils is important to geotechnical engineering practice, such as when assessing the rate of settlement of shallow foundations, embankments, and landfills. In this paper, numerical analyses are performed ...
Multiagent Spatial Simulation of Autonomous Taxis for Urban Commute: Travel Economics and Environmental Impacts
Publisher: American Society of Civil Engineers
Abstract: With the likelihood of autonomous vehicle technologies in public transport and taxi systems increasing, their impact on commuting in real-world road networks is insufficiently studied. In this study, an agent-based model ...
Influences of Suction on Plate Load Tests on Unsaturated Silty Sands
Publisher: American Society of Civil Engineers
Abstract: In this study, results of plate load tests performed on saturated and unsaturated silty sand samples are presented. Very little is known about how to interpret the plate load test when performed on unsaturated soils ...
