摘要: — A reanalysis has been carried out on the results of Zachariah. An elastic-plastic analysis based S-N data indicates that mechanism growth very small cracks is similar to expressed by linear elastic fracture mechanics, i.e. crack in mild steel given by where Δγp plastic shear strain range and a length. Crack initiation occurs within single grain propagation above equation for which can be smaller than few microns. The size an initiated function stress level varying from 0·1–1·0 μm high fatigue regime 2·3 close limit. period negligible HSF whilst dominate lifetime at low levels.
