Multiple-cracked fatigue crack growth by BEM
Computational Mechanics, 1995The dual boundary element method is applied to the two-dimensional linear elastic analysis of fatigue problem of multiple-cracked body. For each crack, the traction integral equation is applied on one surface of the crack, while the usual displacement integral equation is used simultaneously on the other. General multiple crack growth problem is solved

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

THE FATIGUE BEHAVIOUR OF CRACKED CONCRETE
Fatigue & Fracture of Engineering Materials & Structures, 1997Abstract— Cracks are among the most common flaws in civil engineering structures and, considering the cyclic nature of the variable loading patterns, it is evident that the evaluation of the structure safety factor should consider the stability of cracks when fatigue loading occurs.In the present paper, the behaviour of cracked concrete subjected to ...

Monitoring fatigue cracks in gears
NDT & E International, 1991Abstract Vibration analysis is the most common means of gear monitoring and diagnostics. Gear vibration is affected by faults but the signal is usually picked up at the case, where it is also affected by the structural response. An appropriate filtering function is therefore proposed to recover the torsional gear vibration from the case vibration ...

Fatigue Crack Propagation of Short Cracks
Journal of Engineering Materials and Technology, 1979Previous studies have shown that both threshold stress intensity factors and fatigue crack growth rates are dependent on crack size. The average growth rates for very short cracks considerably exceed those given by conventional stress intensity-crack growth laws fitted to long crack data.
