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

Finite element analysis of plasticity - induced fatigue crack closure using contact elements [PDF]
WIT Transactions on The Built Environment, 2010 To predict crack opening stresses, contact elements are incorporated into the elastic-plastic finite element analysis of fatigue crack closure. A code using ANSYS Parametric Design Language (APDL) is developed.

Extension of the CJP model to mixed mode I and mode II [PDF]
Fracture and Structural Integrity, 2013 The present authors have previously proposed a novel ‘plastic inclusion’ approach for dealing with the local plasticity which occurs at the tip of a growing fatigue crack.

Investigation of plasticity-induced fatigue crack closure [PDF]
Australian Journal of Mechanical Engineering, 2007 Plasticity induced crack closure and constraint effects due to finite plate thickness are both fundamental aspects in the mechanics of fatigue cracks. Moreover, plasticity induced crack closure provides an effective first-order correction to the crack ...

Effect of crack propagation on crack tip fields [PDF]
Fracture 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.

Crack tip strain evolution and crack closure during overload of a growing fatigue crack [PDF]
Fracture and Structural Integrity, 2017 It is generally accepted that fatigue crack growth is retarded after an overload, which has been explained either by plasticity-induced crack closure or near-tip residual stress.

An analytical model of plasticity induced crack closure
Procedia Engineering, 2010 AbstractAccurate and non-conservative measurements of fatigue crack growth rate are essential when designing efficient structures to be subjected to cyclic loading. Crack closure is a main mechanism of fatigue crack propagation and must be included.

Plasticity induced crack closure: a sensitivity analysis [PDF]
, 2012 Plasticity induced crack closure (PICC) is closely linked to the monotonic and reversed plastic deformation occurring at the crack tip. The objective of the paper is to identify the different physical and numerical parameters affecting PICC, and ...
