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 ...

An embedded crack model for failure analysis of concrete solids [PDF]
, 2010 We present a quadrilateral fi nite element with an embedded crack that can be used to model tensile fracture in two-dimensional concrete solids and the crack growth. The element has kinematics that can represent linear jumps in both normal and tangential

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.

Mode Localization of a Cracked Blade-Disks [PDF]
Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education, 1998 In this paper, the effect of blade crack on the mode localization of a rotating blade-disk is studied. Pretwisted taper beams are used to simulate blades of a blade-disk. The crack on the blade can be regarded as a local disorder of this periodically coupled blades system.
