Experimental and Finite Element Modeling of Near-Threshold Fatigue Crack Growth for the K-Decreasing Test Method [PDF]

The experimental methods to determine near-threshold fatigue crack growth rate data are prescribed in ASTM standard E647. To produce near-threshold data at a constant stress ratio (R), the applied stress-intensity factor (K) is decreased as the crack ...

Mode 1 delamination growth in adhesively bonded joints under static and fatigue loads [PDF]

The objective of this investigation was to characterize the pure mode 1 delamination growth in metal to metal adhesively bonded joints under static and fatigue loading conditions, using FM 73 adhesive. Double cantilever beam specimens (DCB) were used for

Grain boundary oxidation and its effects on high temperature fatigue life [PDF]

Fatigue lives at elevated temperatures are often shortened by creep and/or oxidation. Creep causes grain boundary void nucleation and grain boundary cavitation.

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 ...

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.

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.

Rate transitions in the fatigue crack growth of elastomers

Journal of Applied Polymer Science, 2008
AbstractIt has been observed previously that cracks in elastomers under repeated strain initially grow rapidly from sharp cuts, but as the cracks proceed, the rate decreases to a steady value. This work examines these transitions from a sharp crack tip, introduced by a razor blade into a pure shear test piece, for a range of elastomers.
