Insulated rail joints are widely used in railway network infrastructure for connecting rail segments. Failure of this safety component might result in serious accident and life lost. One of the failure modes of the rail joints assembly is cracking of the joint bar due to the high stress. The main challenge for optimization the shape of the joint bar is the dynamic analysis of the joint bar and calculating the maximum stresses. In this study, however some analysis have been conducted to simulate the joint bar behavior as close as possible to the real situation. The ANSYS finite element program is used to simulate the loading and boundary conditions of the joint bar for a stress analysis. The obtained results may be used for optimization procedure.
