Multiple-cracked fatigue crack growth by BEM

Computational Mechanics, 1995
The 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, 1993
AbstractAn 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, 1997
Abstract— 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 ...

Fatigue Crack Propagation of Short Cracks

Journal of Engineering Materials and Technology, 1979
Previous 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.
