Engineering Analysis with Boundary Elements, 1989 Abstract This paper deals with the determination of stress intensity factors for plane cracks which are at or near interfaces. The interface may be straight or curved and be a free surface or between two elastically dissimilar materials. Any bulk stress field may be catered for as may partially closed cracks.

How to avoid FIB-milling artefacts in micro fracture? A new geometry for interface fracture
Materials & Design, 2023 Focused ion beam (FIB) based small-scale fracture studies have been well established in recent years despite the ongoing discussion of possible artefacts caused by FIB milling. Stable crack growth geometries—where the FIB-prepared notch stably propagates

Damage process of a fiber bundle with a strain gradient [PDF]
, 2008 We study the damage process of fiber bundles in a wedge-shape geometry which ensures a constant strain gradient. To obtain the wedge geometry we consider the three-point bending of a bar, which is modelled as two rigid blocks glued together by a thin ...

International Journal of Fracture, 1994 An analysis of a crack lying along an interface between two elastically dissimilar quarter-planes, and breaking the free surface is given. The method of distributed dislocations is employed and the nominal stress field is taken to be uniform along the length of the line of the crack.

Study on Interfacial Crack Initiation of Jointed Rock Mass Based on Interface Fracture Mechanics
Fractal and Fractional, 2022 The fracture of interfacial crack is the main failure type of jointed rock mass. Therefore, it is very important to study the interfacial fracture of jointed rock mass. For the similarity of jointed rock mass and composites (all are composed by two parts,

Exterior interface cracks [PDF]
International Journal of Engineering Science, 1980 Abstract Continuing a recent investigation of interface cracks, attention is paid to the exterior crack. Two elastic solids bonded over a finite segment of their boundary and capable of transmitting shear and tensile tractions are considered. It is found that one of the edge cracks remains completely closed under shear alone, and opens gradually as ...

Characterisation of microstructure, defect and high-cycle-fatigue behaviour in a stainless steel joint processed by brazing [PDF]
, 2019 We report the characterisation of microstructures and high-cycle-fatigue (HCF) properties of Type 304 stainless steel joints processed by brazing. Pure copper was applied as the filler metal for brazing at 1120 °C. A two-phase microstructure was obtained

Discrepancy between sub-critical and fast rupture roughness: a cumulant analysis [PDF]
, 2006 We study the roughness of a crack interface in a sheet of paper. We distinguish between slow (sub-critical) and fast crack growth regimes. We show that the fracture roughness is different in the two regimes using a new method based on a multifractal ...
