Role of plasticity-induced crack closure in fatigue crack growth [PDF]

open access: yesFracture and Structural Integrity, 2013
The premature contact of crack surfaces attributable to the near-tip plastic deformations under cyclic loading, which is commonly referred to as plasticity induced crack closure (PICC), has long been focused as supposedly controlling factor of fatigue ...

Effect of crack propagation on crack tip fields [PDF]

open access: yesFracture and Structural Integrity, 2013
Crack closure influences fatigue crack growth rate and must be included in the design of components. Plasticity induced crack closure is intimately linked with the crack tip plastic deformation, which becomes residual as the crack propagates.
