## AImWet -Based on the fatigue crack propagation (FCP) expression developed by X. Zheng and M. A. Hirt. a new method for the estimation of FCP rate is suggested. It is pointed out that when Ak;,, (the FCP threshold) and the mechanism in the intermediate region of FCP are known, the FCP rates can
When these data are applied to the formula derived by M. A. Schroedl and C. W. Smith, the stress intensity factor K, can be calculated. Comparing this computed K, with that given by theoretical formula, we have found the error to be within t 5.20%. It is believed that the result of this test has met
In the present paper test results are given to show that a simple formula for fatigue crack propagation (FCP), the derivation of which is based on the modified static fracture model, can give a good fit to the FCP test results of metals where FCP occurs due to the striation mechanism. Additionally,
