Finite Element Analysis of Subsurface Crack Propagation in Half-space Due to Sliding Contact
유한요소법을 이용한 미끄럼 접촉시의 반무한체 내의 수평균열 전파해석
Abstract
Finite element analysis is peformed about the crack propagation in half-space due to sliding contact. The analysis is based on linear elastic fracture mechanics and stress intensity factor concept. The crack location is fixed and the friction coefficient between asperity and half-space is varied to analyze the effect of surface friction on stress Intensity factor for horizontal crack. The crack propagation direction is predicted based on the maximum range of shear and tensile stress intensity factor.
