3654 転がり接触による三次元内部き裂の進展挙動に及ぼす傾斜角度の影響(S24-4 特異応力・刃状転位,S24 数理・数値解析による先端材料評価)

抄録

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.
