Experimental and Discrete Element Modeling of Geocell-Stabilized Subballast Subjected to Cyclic Loading
Publisher: American Society of Civil Engineers
Abstract: This paper presents a study of the load-deformation behavior of geocell-stabilized subballast subjected to cyclic loading using a novel track process simulation apparatus. The tests were conducted at frequencies varying ...
Behavior of Fresh and Fouled Railway Ballast Subjected to Direct Shear Testing: Discrete Element Simulation
Publisher: American Society of Civil Engineers
Abstract: This paper presents the three-dimensional discrete element method (DEM) that was used to study the shear behavior of fresh and coal fouled ballast in direct shear testing. The volumetric changes and stress-strain behavior ...
