(American Society of Civil Engineers, 1987)The method presented in the companion paper is applied herein to analyze the nonlinear earthquake response of an earth dam; the entire time history of the response quantities, including permanent deformation of the dam, ... -
2‐D Elastoplastic Seismic Shear Response of Earth Dams: Theory
(American Society of Civil Engineers, 1987)A simplified analytical‐numerical method for analyzing the nonlinear earthquake response of earth dams, modeled as two‐dimensional, nonhomogeneous shear wedges in rectangular canyons, is presented. The method takes into ... -
2‐D Representation of 3‐D Limit Surfaces
(American Society of Civil Engineers, 1986)Attention is drawn to the nonsymmetry which results when isotropic failure contours are represented in planes σ -
3D Beam‐Column Element with Generalized Plastic Hinges
(American Society of Civil Engineers, 1986)Beam‐column elements in which plastic hinges may form are commonly used for elastic‐plastic analysis of frames. The concept of a zero‐length plastic hinge (lumped plasticity) is a mathematical abstraction, because it implies ... -
3D Digital Analysis of Cracking Behaviors of Rocks through 3D Reconstruction Model under Triaxial Compression
(ASCE, 8/1/2020 1)The cracking behaviors of rocks significantly affect their mechanical properties. In this paper, a digital analysis approach with X-ray Computed Tomography (CT) imagery is developed to investigate the cracking and mechanical ... -
3D Discrete Solid-Element Method for Elastoplastic Problems of Continuity
(American Society of Civil Engineers, 2018)This paper proposes a novel three-dimensional (3D) discrete solid-element method (DSEM) to calculate the extremely large deformation and high material nonlinearity of continuity. In DSEM, the material is discretized into ... -
3D Dislocation Density–Based Crystal Plasticity Model for Rock Salt under Different Temperatures and Strain Rates
(ASCE, 2021-12-29)Rock salt is a sedimentary rock found in nature as bedded or domal deposits due to evaporating inland seas or any enclosed bodies of saline water. Rock salt hosts caverns within the underground deposits that can potentially ... -
3D Dynamic Elastoplastic Constitutive Model of Concrete within the Framework of Rate-Dependent Consistency Condition
(ASCE, 11/1/2020 )In this paper, the proposed yield function is the function of stress, hardening parameter, and strain rate. To fully describe the stress state and strain rate condition of material during dynamic loading, a new coordinate ... -
3D Elastoplastic Model for Fine-Grained Gassy Soil Considering the Gas-Dependent Yield Surface Shape and Stress-Dilatancy
(ASCE, 2020)Fine-grained sediments containing large discrete gas bubbles are widely distributed in the five continents throughout the world. The presence of gas bubbles could either degrade or enhance the hardening behavior and undrained ... -
3D Finite-Deformation Beam Model with Viscous Damping: Computational Aspects and Applications
(American Society of Civil Engineers, 2015)A nonlinear finite-element formulation for the static and dynamic behavior of flexible beams was developed by appropriately modifying and extending the three-dimensional (3D) finite-deformation beam model originally developed ... -
3D Finite-Element Simulation of a Square Silo with Flexible Walls
(American Society of Civil Engineers, 2001)Most of the studies that have been published to evaluate stresses on silo walls during filling or discharge stages are based on a rigid wall assumption. In a 2D approach, the wall flexibility can be approximately modeled ... -
3D Grain-Based Mesoscale Modeling of Short Fatigue Crack Growth for Bridge Weldments Considering Crack-Front Evolution
