Finite element modeling and simulation of rail steel track loading

This project evaluated the behaviours of the rail track components under static loading conditions. Rail track finite element models were created by using three-dimensional finite element analysis software (FEA) ABAQUS. The objective of these models is to investigate the stresses distribution and de...
