Using a direct proportionality between the rate of fatigue crack growth and crack opening displacement above a threshold, it is shown that fatigue crack growth data for a wide variety of different materials can be accurately described in terms of the mechanical properties and two material constants
The micromechanics of crack initiation and early growth in 4340 steel is studied using the SEM, and it is found that growth is discontinuous and transgranular, with the distance between growth steps corresponding to the prior austenite grain size spread. The lowest observed growth rate is approximat
