Abstract
Polymers have been applied to various industrial fields and used as machine parts and structural members with the swift advance of industry, the usage conditions of polymers have been variously changed, and then the problems of fatigue fracture and of environmental fracture have been intensified. Therefore, the experiment for low cycle fatigue fracture of polycarbonate have been done in this research. Local strain in the vicinity of notch root and crack tip was measured in real time by using fine grid method. The relationships among local strain, crack initiation from notch and crack propagation of crack tip have been studied, and the method for the more precise life estimation was suggested in this paper.
