Computational modeling of three-dimensional mixed mode-I/II/III fatigue crack growth problems and experiments

open access: yesComputers & Structures, 2021
Abstract Mixed mode-I/II/III fatigue crack growth experiments and their simulations are performed using a system permitting all possible combinations of three-dimensional mixed mode loading conditions. The so-called Compact Tension-Shearing and Tearing (CTST) specimens used in the experiments are made of 7075-T651 aluminum alloy. Different mixed mode

Role of hydrogen in hydrogen-induced layer exfoliation of germanium [PDF]

open access: yes, 2007
The role of hydrogen in the exfoliation of Ge is studied using cross-sectional transmission electron microscopy, atomic force microscopy, and multiple-internal transmission mode Fourier-transform infrared absorption spectroscopy and compared with the ...

Fractographic Study on Mode II and Mode III SCC Crack Growth in Al-Zn-Mg Alloy

open access: yesJournal of the Society of Materials Science, Japan, 1984
A fractographic study on mode II and mode III static- and cyclic-SCC crack growth in 3.5% NaCl solution has been carried out for a high-strength Al-Zn-Mg alloy. Static- and cyclic-SCC crack growth was introduced under mode II and mode III loads. Unlike the mode I SCC, the fracture surface morphologies of mode II and mode III SCC were characterized by ...

Quasi-Static Brittle Fracture in Inhomogeneous Media and Iterated Conformal Maps: Modes I, II and III

open access: yes, 2002
The method of iterated conformal maps is developed for quasi-static fracture of brittle materials, for all modes of fracture. Previous theory, that was relevant for mode III only, is extended here to mode I and II.

Crack Front Segmentation and Facet Coarsening in Mixed-Mode Fracture [PDF]

open access: yes, 2015
A planar crack generically segments into an array of "daughter cracks" shaped as tilted facets when loaded with both a tensile stress normal to the crack plane (mode I) and a shear stress parallel to the crack front (mode III).

RETRACTED: The Effect of Treatment Temperature on Microstructure and Mechanical Behavior of a Fine-Grained YSZ–NiO(Ni) Anode Material

open access: yesCrystals, 2023
Reduction–oxidation (redox) cycling of a solid oxide fuel cell (SOFC) due to leakage of a fuel or standby and shutdown cycling is an issue that has attracted the attention of many research groups for a long time.

Fracture characteristics of Brazilian disc with fully internal cracks based on 3D-ILC

open access: yesYantu gongcheng xuebao, 2019
The fully internal crack is created in the Brazilian disc based on the 3D-ILC method, without any effect on the surface. The uniaxial compression experiments are performed on the Brazilian discs with internal cracks at different angles.
