Experimental and simulation study on Ⅰ-Ⅱ mixed-mode fatigue crack growth of TC4-DT welded joint
Journal of Aeronautical Materials, 2020 The crack growth in the structure shows the complex Ⅰ-Ⅱ mixed-mode under the combined tensile and shear fatigue loading. It is of great significance to understand its growth law for evaluating the fatigue life of structures accurately.

The Effect of Temperature and Heating–Cooling Cycles on Mode I, Mode II and Mixed-Mode I-II Fracture Toughness of Sandstone [PDF]
Muhandisī-i manābi̒-i ma̒danī, 2021 In the case of explosions and fires, the rocks undergo a cycle of heating and cooling. For that, first, they are exposed to considerable heat and then cooled after extinguishing the fire.

Crack detection of a beam-like bridge using 3D mode shapes
Vietnam Journal of Mechanics, 2014 In this paper, mode shapes of a 3D cracked beam with a rectangular cross section are analyzed for crack detection. The influence of coupling mechanism between horizontal and vertical bending vibrations due to the 3D crack model on the mode shapes is ...

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

A three-dimensional elastoplastic analysis of mixed-mode KI/KII around the crack front [PDF]
MATEC Web of Conferences, 2019 Engineering problems that involve fatigue crack growth and fracture frequently can be studied by taking into account only mode-I features. However, many important problems that involve combined mode I and II loadings cannot be properly analyzed by a pure

Fatigue crack growth of aluminium alloy 7075-T651 under non-proportional mixed mode I and II loads [PDF]
Fracture and Structural Integrity, 2016 This study aims to investigate fatigue growth behaviour in AA7075-T651 under non-proportional mixed mode I and II loads. Fatigue tests were performed under cyclic tension and torsion using a thin-walled tubular specimen with a key-hole style crack ...

Effect of Initial Debond Crack Location on the Face/core Debond Fracture Toughness
EPJ Web of Conferences, 2010 This paper studies the effect of initial crack location on the face/core debond fracture toughness under different mixed mode loading conditions. The mixed mode loading at the crack tip is defined in terms of the mode-mixity.
