Abstract: The high-speed train key components serve under high speed and overload working conditions for a long time, the safety and service life are widespread concerned. This paper concerns about the failure reason of high-speed train key components and the theory of fracture mechanics in failure assessment. we also discuss the feasibility of fracture mechanics applied in failure analysis and residual life evaluation application.
