Effects of microstructure and crystallography on crack path and intrinsic resistance to shear-mode fatigue crack growth [PDF]

open access: yesFracture and Structural Integrity, 2015
The paper focuses on the effective resistance and the near-threshold growth mechanisms in the ferritic-pearlitic and the pure pearlitic steel. The influence of microstructure on the shear-mode fatigue crack growth is divided here into two factors: the ...

On the connection between mode II and mode III effective thresholds in metals [PDF]

open access: yesFracture and Structural Integrity, 2017
Closure-free long cracks under the remote mode III loading grow in a more complicated way than those under the remote mode II. For bcc metals, a coplanar in-plane spreading of tongues driven by the local mode II loading components at crack-front ...

3D Analyses of crack propagation in torsion [PDF]

open access: yesFracture and Structural Integrity, 2015
The initiation and propagation of fatigue cracks during cyclic torsion loading was studied in a cast Al alloy (A357) with a relatively large (~500 ?m) grain size.

Variable mode-mixity during fatigue cycles – crack tip parameters determined from displacement fields measured by digital image correlation [PDF]

open access: yesFracture and Structural Integrity, 2017
This paper focusses on discussing equivalent stress intensity factors and kink angles after a change of mode-mixity from one cycle to the next and when the mode-mixity changes continuously during the fatigue cycles.

Analysis of Mixed-Mode I/II/III Fracture Toughness Based on a Three-Point Bending Sandstone Specimen with an Inclined Crack

open access: yesApplied Sciences, 2021
The crack-propagation form may appear as an arbitrary mixed-mode fracture in an engineering structure due to an irregular internal crack. It is of great significance to research the mixed-mode fracture of materials with cracks.

Crack front segmentation under combined mode I- and mode IIIloading [PDF]

open access: yesFracture and Structural Integrity, 2016
This article approaches the topic of crack initiation and crack growth behaviour under combined mode I- and mode III-loading conditions. Such loading combinations especially lead to a crack, which unscrew out of its initial orientation and segments into ...

Experimental study on 3D internal penny‐shaped crack propagation in brittle materials under uniaxial compression

open access: yesDeep Underground Science and Engineering, 2023
Fractures are widely present in geomaterials of civil engineering and deep underground engineering. Given that geomaterials are usually brittle, the fractures can significantly affect the evaluation of underground engineering construction safety and the ...

Averaged strain energy density estimated rapidly from the nodal stresses by FEM for cracks under mixed mode loadings including the T-stress contribution

open access: yesFracture and Structural Integrity, 2019
The present contribution reviews a recently proposed method to rapidly estimate the averaged SED at the tip of short as well as long cracks under in-plane I+II and long cracks under out-of-plane I+III mixed mode loadings.

Fatigue crack path and threshold in Mode II and Mode III loadings

open access: yesEngineering Fracture Mechanics, 2008
Abstract In order to investigate the crack path under Mode II or Mode III loadings, reversed torsion tests were carried out on SAE52100 and Mode II fatigue crack growth tests were carried out on 0.47% carbon steel specimens. In the torsional fatigue test (SAE52100), the type of inclusion at the torsional fatigue fracture origin was slender MnS ...

About the impact behavior of woven-ply carbon fiber-reinforced thermoplastic- and thermosetting-composites: A comparative study [PDF]

open access: yes, 2013
This study is aimed at comparing the response of TS-based (epoxy) and TP-based (PPS or PEEK) laminates subjected to low velocity impacts. C-scan inspections showed that impact led to diamond-shaped damage resulting from different failure mechanisms ...
