What is 2020 JCR2 MacroMeso Dynamic Analysis of Railway Transition Zone Hybrid DEMFDM Simulation and Experimental Validation about?

This study presents a hybrid numerical model combining the Discrete Element Method (DEM) and Finite Difference Method (FDM) to analyze the mechanical behavior of railway transition zones. The model simulates the ballast bed and sleeper using DEM while employing FDM for the track substructure, validated through field measurements. Results indicate that incorporating wedge-shaped backfill significantly mitigates track vibration and stress changes at the transition zone, enhancing overall dynamic performance.
