Interaction between line cracks in an orthotropic layer

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
We deal with the interaction between three coplanar Griffith cracks located symmetrically in the mid plane of an orthotropic layer of finite thickness 2h. The Fourier transform technique is used to reduce the elastostatic problem to the solution of a set

Report on Phase 2.3, Investigation of Welded Highway Bridges. Project IHR-64 [PDF]

open access: yes, 1973
The object of this investigation was to study the effect of internal flaws on the fatigue behavior of butt-welded connections in mild structural steel, the initiation of fatigue cracks from these flaws and the propagation rates of these cracks in the ...

Crack propagation in non-homogenous materials: Evaluation of mixed-mode SIFs, T-stress and kinking angle using a variant EFG method [PDF]

open access: yes, 2016
A new variant of the Element-Free Galerkin (EFG) method, that combines the diffraction method, to characterize the crack tip solution, and the Heaviside enrichment function for representing discontinuity due to a crack, has been used to model crack ...

Effect of grain structure on fatigue crack propagation behavior of 2024 aluminum alloy under different stress ratios

open access: yesMaterials & Design
The fatigue load that a material experiences and its microstructure are important factors influencing fatigue crack propagation behavior. This study employed laser scanning microscopy and electron backscatter diffraction (EBSD) technology, along with ...

Crackling noise in three-point bending of heterogeneous materials [PDF]

open access: yes, 2011
We study the crackling noise emerging during single crack propagation in a specimen under three-point bending conditions. Computer simulations are carried out in the framework of a discrete element model where the specimen is discretized in terms of ...

Temperature and load-ratio dependent fatigue-crack growth in the CrMnFeCoNi high-entropy alloy [PDF]

open access: yes, 2019
Multiple-principal element alloys known as high-entropy alloys have rapidly been gaining attention for the vast variety of compositions and potential combinations of properties that remain to be explored. Of these alloys, one of the earliest, the ‘Cantor

Nonuniformly Loaded Stack of Antiplane Shear Cracks in One-Dimensional Piezoelectric Quasicrystals

open access: yesAdvances in Materials Science and Engineering, 2018
Representations in a closed form are derived, using an extension to the method of dislocation layers, for the phonon and phason stress and electric displacement components in the deformation of one-dimensional piezoelectric quasicrystals by a ...

On the Mechanistic Origins of Toughness in Bone [PDF]

open access: yes, 2010
One of the most intriguing protein materials found in nature is bone, a material composed of assemblies of tropocollagen molecules and tiny hydroxyapatite mineral crystals that form an extremely tough, yet lightweight, adaptive and multifunctional ...

Interfacial adhesion of laser clad functionally graded materials [PDF]

open access: yes, 2003
Specially designed samples of laser clad AlSi40 functionally graded materials (FGM) are made for evaluating the interfacial adhesion. To obtain the interfacial bond strength notches are made right at the interface of the FGMs.
