The Study of Fatigue Life of Cold-Recycled Base Material Based on the Fracture Mechanics Method
The method of fracture mechanics is used to analyse the fatigue crack propagation of cold-recycled base material in this paper. The suitable fracture mechanics formula and parameters are choosen and then we deduce the fatigue life forecast equation.After that we annlyse the method of determineing parameters and give the axample.The conclusion is gained through comparing with the database obtained from the experiment .It is more reasonable to forecast the fatigue life of cold-recycled base material with crack based on the method of fracture mechanics.
