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 ...

Energy Exploration & Exploitation, 2022 The macroscopic failure of concrete used to form an artificial dam in an underground coal mine reservoir is the final manifestation of crack propagation and penetration: the mode of crack propagation is key to the safety evaluation of concrete structures.

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 ...

A cohesive XFEM model for simulating fatigue crack growth under mixed‐mode loading and overloading
International Journal for Numerical Methods in Engineering, 2019 Structures are subjected to cyclic loads that can vary in direction and magnitude, causing constant amplitude mode I simulations to be too simplistic. This study presents a new approach for fatigue crack propagation in ductile materials that can capture ...

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.

Rail fatigue crack propagation in high-speed wheel/rail rolling contact
Journal of Modern Transportation, 2017 To study the wheel/rail rolling contact fatigue of high-speed trains, we obtain the distribution of contact forces between wheel and rail by introducing the strain-rate effect.

Fatigue crack detection in pipes with multiple mode nonlinear guided waves
Structural Health Monitoring, 2018 This study elaborates fundamental differences in fatigue crack detection using nonlinear guided waves between plate and pipe structures and provides an effective approach for analysing nonlinearity in pipe structures.
