    <description descriptionType="Abstract">&lt;p&gt;The goal of this study is analyzing and identifying the stresses on bolted rail joint due to the&lt;br&gt;
wheel load to predict and minimize failures caused. The three dimensional model has been&lt;br&gt;
developed on modeling package of CATIAV5R16. In CATIAV5R16, different components of&lt;br&gt;
wheel/rail assembly i.e. wheel, rail, joint, bars, nuts, bolts are created separately then all&lt;br&gt;
components are assembled, and create a complete model of wheel/rail assembly. Assembly&lt;br&gt;
model has created in assemble workbench of CATIA after individual component of joint had&lt;br&gt;
created on part work bench. After the assembly is accomplished on CATIA, it was imported in to&lt;br&gt;
the ANSYS v14.5 to analyze the stress caused by vertical load. The material properties of the rail&lt;br&gt;
and wheel are assumed to be same. All the material properties and boundary conditions are being&lt;br&gt;
applied to estimate fatigue stress. The analysis using the software ANSYS includes fatigue&lt;br&gt;
stress, fatigue life, von miss stresses, shear stress and Equivalent elastic strain. These values have&lt;br&gt;
been determined under the influence of axle load. The result obtained in this analysis is better&lt;br&gt;
stress values for rail joint assembled by the modified geometry than the existing joint bar. During&lt;br&gt;
the rail joint analysis Joint between the sleepers needed more attention than other parts, to reduce&lt;br&gt;
the problem related to the rail joint.&lt;/p&gt;</description>
