Analysis of Closure in Fatigue Crack Growth
Journal of Applied Mechanics, 1978A theoretical study is made of the implications of a Dugdale-Barenblatt model for fatigue crack growth under steady cyclic loading. Residual plastic stretches and the effects of crack closure on crack opening and closing loads are calculated by complex function methods for a range of loading ratios.

THE EFFECT OF ARTIFICIAL FATIGUE‐CRACK CLOSURE ON FATIGUE‐CRACK GROWTH
Fatigue & Fracture of Engineering Materials & Structures, 1993AbstractAn investigation of the effects of artificial fatigue‐crack closure on the subsequent growth of fatigue cracks, at constant range of stress‐intensity factor, was carried out for the following closure materials: (i) electroplated nickel; (ii) electroless nickel; (iii) ethylcyanoacrylate (ECA) adhesive; (iv) low‐melting point (LMP) solder. It was

Metal fatigue is a major cause for failure of mechanical and structural components. We review the fracture mechanics of fatigue and Paris-Erdogan law for the mean behavior. After a consideration of experimental data reported by Virkler et al. (1979), we propose a continuous semimarkov process to model crack growth.

Fatigue crack growth in polyethylene
Polymer Engineering & Science, 1985AbstractFatigue crack propagation (FCP) rates are studied in 6 mm thick specimens of high density polyethylene (HDPE) containing razor notches, Centrally‐notched plates and single‐edg notched bars are subjected to sinusoidal tension‐compressio or tension‐zero cycling at 0.5 or 2.0 Hz under load control a room temperature; crack growth is monitored ...

CRACK GROWTH AS AN INTERPRETATION OF STATIC FATIGUE
Journal of Non-Crystalline Solids, 1975Abstract Static fatigue is due to water in the environment which accounts for substantial reductions in the strength of glass. Extensive experimental investigations have shown that static fatigue results from surface cracks that grow when glass is subjected to tensile loads. In this paper evidence for this conclusion is reviewed.

Growth of fatigue cracks in steels
Metal Science, 1976AbstractAn extensive study of fatigue-crack growth in BS15 mild steel has been made, in laboratory air at 21°C and at two cycling frequencies, namely 0.25 and 35 Hz. A wide range of cyclic growth rates, starting from the region associated with fatigue thresholds (10−7 mm/cycle) up to the region of rapid fracture, was investigated using contoured DCB ...

In this chapter the main factors influencing high temperature creep—fatigue crack growth in engineering materials are discussed. The significance of minimum to maximum load ratio R, frequency, environment and temperature are considered in turn. Transgranular cycle dependent and intergranular time dependent controlled cracking processes are identified ...

Fatigue crack growth in polymers
International Journal of Fracture, 1980A number of fatigue crack propagation laws applied in the study of polymers is described. Consideration of the stress field distribution at the crack tip leads to the application of fracture mechanics. It is shown that a simplified relationship of the form da/dN =Fλα, whereφ is a function ofKIC,Kmax,Kmin andKTH appears to be a convenient expression for

The importance of delay, or retardation in the rate of fatigue crack growth, produced by load interactions in variable amplitude loading on the accurate prediction of fatigue lives of engineering structures has been well recognized for some time. Heretofore, only a few simple loading combinations or spectra have been examined systematically.
