A phenomenological constitutive model considering crack closure effect of thermally damaged rock [PDF]
Scientific ReportsCrack closure behavior is an important part in stress-strain curve of brittle rock; however, the crack closure effect is seldom described in previous constitutive models.

Effect of crack closure on non-linear crack tip parameters [PDF]
International Journal of Fatigue, 2015 Abstract Crack closure concept has been widely used to explain different issues of fatigue crack propagation. However, some authors have questioned the relevance of crack closure and have proposed alternative concepts. The main objective here is to check the effectiveness of crack closure concept by linking the contact of crack flanks with non-linear

Crack closure effect of fatigue crack under cyclic tensile loading
Nihon Kikai Gakkai ronbunshu, 2015 The objective of this study is to evaluate crack growth behavior under cyclic tensile loading considering crack closure effect. Crack growth behavior under cyclic tensile loading on a plate with surface crack is tested.

Study of Crack Closure Effect of Hull Plate under Low Cycle Fatigue
Journal of Marine Science and Engineering, 2022 The crack closure phenomenon significantly influences low cycle fatigue (LCF) crack growth. The crack closure theory deems that a crack can grow only when the applied load is greater than the fatigue crack opening and closing loads.

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.

Effects of closure on the detection probability of fatigue cracks [PDF]
The Journal of the Acoustical Society of America, 1981 Fatigue cracks often can be (more or less) tightly closed. Under such “closure” conditions the crack may be transparent to ultrasound and actually form electrical contact between fracture surfaces, diminishing the eddy current response with respect to the fully open 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.
