3654 Influence of Inclined Angle to Three Dimensional Internal Crack Growth Behavior due to Repeated Rolling Contact

Abstract

In this study, three dimensional internal inclined crack growth behaviors due to repeated rolling thermoelastic contact were considered. In this analysis, crack is modeled as an internal inclined planar crack in a three dimensional half-space. Rolling contact is simulated as a long and narrow distributed load with both normal and shear components moving with constant velocity. The shapes of crack contour are calculated under various conditions, which change angle of inclined crack.
