Interacting Multiple Cracks [PDF]

open access: yesKey Engineering Materials, 1997
A method is presented to solve the plane elastic problem of a solid weakened by numerous cracks. The method provides an efficient computational procedure to solve crack interaction problems. Besides non-intersecting multiple open cracks, the method can tl eat intersectional cracks, surface contact cracks or even partial surface contact cracks.

Effect of grain disorientation on early fatigue crack propagation in face-centred-cubic polycristals: A three-dimensional dislocation dynamics investigation [PDF]

open access: yes, 2013
Three-dimensional dislocation dynamics simulations are used to study micro-crack interaction with the first micro-structural barrier in face-centred cubic bi-crystals loaded in high cycle fatigue conditions. In the examined configuration, we assumed that

Propagation of double internal cracks under uniaxial tension based on 3D-ILC

open access: yesYantu gongcheng xuebao, 2019
The multiple-crack interaction is an important research topic in fracture mechanics, but few studies have focused on the interaction of 3D internal cracks under uniaxial tension. 3D double internal cracks are generated based on 3D-ILC.

Numerical Simulation on Crack–Inclusion Interaction for Rib-to-Deck Welded Joints in Orthotropic Steel Deck

open access: yesMetals, 2023
Weld defects such as porosity, inclusion, burn-through, and lack of penetration are difficult to detect and control effectively in an orthotropic steel deck (OSD), which will be a fatigue crack initiation site and lead to several fatigue cracking.

Modeling of edge cracks interaction [PDF]

open access: yesFracture and Structural Integrity, 2016
From experimental and theoretical investigations it is known that cracks are sensitive to geometry, e.g., to the inclination angle to the load. A small deviation of a crack from the normal direction to a tensile load causes mixed mode conditions near the

Mechanism of crack branching in the fatigue crack growth path of 2324-T39 Aluminium alloy [PDF]

open access: yesFracture and Structural Integrity, 2016
The crack growth behavior in 2324-T39 aluminium alloy was experimentally investigated. Two types of crack branching were observed. The mechanism of an uncommon crack branching which results from the link up of secondary crack with the main crack was ...

Crack interaction with microstructure

open access: yesMaterials Today, 2007
Designing microstructure for damage tolerance requires a detailed understanding of how an advancing crack interacts with the microstructure (and sometimes modifies it locally) at multiple length scales. Advances in experimental techniques, such as the availability of well-controlled straining stages for optical and electron microscopes, the focused ion

Fitness-for-Service Analysis of the Interplay Between a Quarter-Circle Corner Crack and a Parallel Semi-Elliptical Surface Crack in a Semi-Infinite Solid Subjected to In-Plane Bending Part II—The Effect on the Semi-Elliptical Surface Crack

open access: yesApplied Sciences
The impact of a quarter-circle corner crack on an adjacent parallel semi-elliptical surface crack (SESC) located in a semi-infinite solid subjected to in-plane bending is studied using a 3-D finite element analysis.
