RISDisturbed State Concept-Based Constitutive Model for Lignosulfonate-Treated Silty Sand
Publisher: American Society of Civil Engineers
Abstract: In this paper, a new behavioral (plasticity) model for lignosulfonate (LS)–treated silty sand based on the disturbed state concept is proposed. Here, the relative intact (RI) responses for both the LS-treated and untreated ...
Behavior of Steel Furnace Slag, Coal Wash, and Rubber Crumb Mixtures with Special Relevance to Stress–Dilatancy Relation
Publisher: American Society of Civil Engineers
Abstract: The influence of rubber crumbs on the dilatancy behavior and critical state of steel furnace slag (SFS), coal wash (CW), and rubber crumbs (RC) mixtures was investigated via a series of monotonic drained triaxial tests. ...
Behavior of Sand–Tire Chip Mixtures in Constant Shear Drained Stress Path
Publisher: ASCE
Abstract: This paper presents the potential of scrap tire in controlling the onset of instability of sand in the constant shear drained (CSD) stress path. A series of triaxial tests in the constant shear drained stress path was ...
Numerical Modeling of Cone Penetration Test: An LBM–DEM Approach
Publisher: ASCE
Abstract: In this paper, the discrete element method (DEM) is coupled with the Lattice Boltzmann method (LBM) to model the cone penetration test (CPT) of a saturated granular media. The coupled numerical model was calibrated using ...
Swelling Behavior of Basic Oxygen Furnace Slag and Granulated Blast Furnace Slag Mixtures: A Laboratory Investigation
Publisher: ASCE
Abstract: Slag, a by-product of the iron and steelmaking industry, has been identified as an alternative construction material; however, there are currently limited engineering reuse applications for some slags. Steel slag coarse ...
Effect of Rubber Crumbs on the Cyclic Behavior of Steel Furnace Slag and Coal Wash Mixtures
Publisher: American Society of Civil Engineers
Abstract: The practical application of waste materials such as steel furnace slag (SFS) and coal wash (CW) is becoming more prevalent in many geotechnical projects. While adding rubber crumbs (RCs) from recycled tires into mixtures ...
Semiempirical Cyclic Densification Model for Ballast Incorporating Particle Breakage
Publisher: American Society of Civil Engineers
Abstract: A number of constitutive models exist to model behavior of granular material under cyclic loading. Most of these models are useful to model soil behavior where the number of cycles is very small. Therefore, a semiempirical ...
Experimental and Numerical Study of Railway Ballast Behavior under Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: This paper presents the results of the influence of frequency on the permanent deformation and degradation behavior of ballast during cyclic loading. The behavior of ballast under numerous cycles was investigated through ...
Multilaminate Mathematical Framework for Analyzing the Deformation of Coarse Granular Materials
Publisher: ASCE
Abstract: Coarse granular materials such as railway ballast and rockfill are often subjected to three-dimensional (3D) stress conditions including the influence of intermediate principal stress. Modeling the deformation and breakage ...
