Determination of fracture mechanics parameters on a base of local displacement measurements [PDF]

open access: yesFracture and Structural Integrity, 2013
New experimental technique for a determination of the stress intensity factor (SIF) and T-stress values is developed and verified. The approach assumes combining the crack compliance method and optical interferometric measurements of local deformation ...

Determination method of fatigue strength and precursors of fatigue failure of porous weakly cemented siltstone

open access: yesMeitan xuebao, 2023
In order to study the fatigue behavior of porous weakly cemented siltstone, a quantitative calculation method of characteristic stress was established based on uniaxial step loading and unloading tests of siltstone.

Damage accumulation near the cold-expanded hole due to high-cycle fatigue by crack compliance method

open access: yesFracture and Structural Integrity, 2022
The novel destructive method is implemented for quantitative assessment of fatigue damage accumulation in the stress concentration zone accompanied by residual stress due to cold expansion of the through-thickness hole.

Crack propagation under variable amplitude loading [PDF]

open access: yesMaterials Research, 2013
Experience shows that a damage induced by a given cycle is dependent on the loading history. In this regard, the objective of this paper is to study and describe the phenomenology of the loading history on crack propagation.

Determining mode I cohesive law of Pinus pinaster by coupling double cantilever beam test with digital image correlation [PDF]

open access: yesFracture and Structural Integrity, 2015
The direct identification of the cohesive law in pure mode I of Pinus pinaster is addressed. The approach couples the double cantilever beam (DCB) test with digital image correlation (DIC).

The effect of low-cycle fatigue on evolution of fracture mechanics parameters in residual stress field caused by cold hole expansion [PDF]

open access: yesFracture and Structural Integrity, 2019
Localized displacement measurements based on electronic speckle-pattern interferometry are used to obtain crack mouth opening displacement (CMOD), stress intensity factor (SIF) and T-stress values during crack growth around cold-expanded holes.

Residual Stress Prediction in Multi-layer Butt Weld Using Crack Compliance Method [PDF]

open access: yesJournal of the Korean Welding and Joining Society, 2012
Abstract It depends on the joint configuration, dimensions and constraints of the joint whether the residual stress at the root of single-sided butt weld is tensile or not. Therefore, recommendation is generally made that highR ratio should be used in the fatigue test of welded joint in order to prevent excessively long life caused by compressive ...

Lengthwise Fracture Study of Transversely Inhomogeneous Rods

open access: yesEngineering Transactions, 2020
A lengthwise crack in a rod that exhibits smooth (continuous) material inhomogeneity in the transverse direction is studied. The rod has a circular cross-section. The lengthwise crack is located arbitrarily along the thickness of the rod.

The compliance approach for analyzing biomaterial interface cracks

open access: yesComputer Assisted Methods in Engineering and Science, 2023
A numerical method is presented for analyzing the mixed mode interface crack between two dissimilar isotropic materials. A simple and efficient solution procedure is developed based on the finite element method and the compliance approach in conjunction
