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

Crack propagation under variable amplitude loading [PDF]
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.

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