Notes:
This paper presents a simulation analysis of stress and strain of an underground railelastic bar using the commercial finite-element simulator ANSYS-10. Under constant compressiondisplacement of 10.4 mm or the fixed-plug-in displacement of 84 mm, the stress distributions areexamined by varying the boundary condition of the corresponding fixed-plug-in displacement or thecompression displacement. Results show that the maximum stress which is 1,490 Mpa occurs as thecompression displacement is 10.4 mm while the fixed-plug-in displacement is 84 mm. In addition,in both group of scenarios the maximum stress is at the end of the arc of the elastic bar and exceedsthe strength limit of 60Si2Mn. While both the compression displacement and the fixed-plug-indisplacement affect the stress distribution and the maximum stress, it appears that the effect due tocompression displacement is much more significant
