Abstract

The sliding contact between two components is one of important phenomenon in engineering applications. Several existing models approach to sliding contact between two surfaces with a sliding model of hemisphere or ellipsoid body. The model presented in this work is done by a condition without and with friction which uses the elasticplastic material, then it is applied a vertical displacement loading. The sliding between ellipsoid is performed with different sliding directions and radius ratio variations that is in the direction Rx and Ry. This final project discuss about von Misses stress value calcutation when the sliding occurs without and with friction condition, comparing the reaction force at sliding with a vertical displacement loading. The result shows the comparison between von Misses stress value with friction is higher than frictionless condition. It can be seen from the result of the plot reaction force at the time of sliding, it can be concluded that reaction force will be higher with the addition of vertical displacement and radius variation that has influence towards von Misses stress value because of the larger area influence that is contacted each other between ellipsoid.
