Abstract—A Strip‐Yield Model for Notched Components (SYMNC) model which employs Newman's method of simulating crack closure and determining the effective stress‐intensity factor is used to predict the fatigue crack growth behavior of non‐stress relieved and stress relieved welded joints.

International Journal of Fracture, 1995
Progressive radial cracking of a clamped plate subjected to crack-face closure is studied. The material behavior is assumed to be elastic-brittle. The cracks are assumed to be relatively long in the sense that the three-dimensional contact problem can be described via a statically equivalent two-dimensional idealization.

Analysis of crack-dislocation interaction: crack closure, crack opening
Materials Science and Engineering: A, 1994Abstract The decrease in stress intensity factor, expected from dislocation emission at a crack tip, can be achieved either through a change in crack tip radius (blunting) or through a crack closure induced by the dislocation (shielding) opposite to the opening imposed by the external stress field.

Crack tip closure and environmental crack propagation
Engineering Fracture Mechanics, 1975Abstract Crack propagation rate, da/dN, and crack tip closure stress, σcc, in part-through crack fatigue specimens of aluminum alloys are drastically affected by gaseous environments. The present studies indicate that the crack closure reflects the influence of the environment on the plastic deformation at the crack tip, and, therefore, on the crack ...

Effect of crack closure on gear crack propagation
International Journal of Fatigue, 2001Computational and experimental studies were performed in order to investigate the propagation of cracking in a spur gear tooth. The stress intensity factors were numerically calculated by the definition of weight functions and by finite element analysis.

Abstract A loading stage for the scanning electron microscope has been used in conjunction with the stereoimaging technique to study fatigue crack closure for a center notched specimen of an aluminum alloy. The results are compared to similar measurements from single edge notched specimens of the same alloy and other materials.
