Fatigue Crack Growth Rate Data Assessment

Volume 4: Materials and Fabrication, 2021
Abstract A comprehensive fatigue test database was developed in PRCI SIA-1-1 and IM-3-2 projects, where there are 185 sets of fatigue crack growth rate parameters (i.e., C and m fitting coefficients in the Paris law) calculated from compact tension (CT) fatigue test data.

Crack opening displacement and the rate of fatigue crack growth

International Journal of Fracture Mechanics, 1972
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 constant of proportionality A and the threshold ...

Fatigue crack growth rates in a porous metal

International Journal of Fatigue, 1980
Abstract Fatigue crack growth rates were studied in A1S1 4600 alloy steel containing various levels of porosity. The materials used for the study were prepared using powder metallurgical techniques, with porosity content controlled by hot press-forging of sintered billets.

A Probabilistic Approach to Fatigue Crack Growth Rate

Journal of Engineering Materials and Technology, 1980
A probabilistic model for fatigue crack growth proposed by K. P. Oh is modified in some respects. Under more natural assumptions than Oh’s it is derived that the rate of fatigue crack growth is proportional to some power of the range of the stress intensity factor. It is also shown that the exponent ranges from 2 to 4.
