J-积分在镀层基体平面压痕边界开裂中的应用
Applications of J-Integral in Fracture Beneath Bearing Surface of Layered Substrate
摘要
Abstract
When a rigid ,flat-ended uniform indenter was pressed on the surface of a layered substrate ,a singular stress field and K-dominant region should arise adjacent to the indentation edges .The indentation stress intensity factor is also a fracture parameter similar to the mode I crack ,which represents the intensification of the stress fields .In present article ,a method to formulize the ISIF for the singular stress fields induced by indentation is proposed based on the conservation integral .关键词
