The theoretical study is advanced to describe quantitatively the crack propagation under cyclic loads. The main assumptions accepted are: (a) a crack grows by loading during every cycle, and (b) the specific dissipation energy is a material constant. The latter contains. the known concept by Irwin a
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
