RISEvaluating the Impact of Mudstone Swelling on Railway Heave of Ballastless Tracks in the Transition Section Using the DEM-FDM Coupling Method
Publisher: American Society of Civil Engineers
Abstract: Mudstone is widely distributed in various regions of northwest China. Due to its high susceptibility to swelling when exposed to water, constructing high-speed railways in shale-prone areas often leads to track heave issues. ...
Frictional Temperature Field and Wear Behavior of Steel 52100 With Different Microstructures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the frictional temperature fields and the wear resistance of steel 52100 with different microstructures during dry sliding were studied by wear testing and computer simulation for ...
Dimethyl Sulfoxide Separating Waste Printed Circuit Boards by Dissolving Polymer Materials
Publisher: American Society of Civil Engineers
Abstract: The separation of waste printed circuit boards (WPCB) has been a bottleneck in WPCB resource processing. In this study, the separation of WPCBs was performed using dimethyl sulfoxide (DMSO) as a solvent by dissolving polymer ...
Analytical Solution to Cylindrical Cavity Expansion in Mohr–Coulomb Soils Subject to Biaxial Stress Condition
Publisher: ASCE
Abstract: In this paper, a semianalytical approach is presented to formulate an excavated cavity in Mohr–Coulomb soils subject to biaxial initial stresses. The response of cavity expansion within the plastic region was investigated ...
