Reduced Fracture Toughness of Metallic Glass at Cryogenic Temperature
Metals, 2017 The effects of cryogenic temperature on the toughness of a Zr-based metallic glass are investigated. Based on three-dimensional fracture morphologies at different temperatures, the crack formation and propagation are analyzed.

Three dimensional microstructural effects on plane strain ductile crack growth
, 2005 Ductile crack growth under mode 1, plane strain, small scale yielding conditions is analyzed. Overall plane strain loading is prescribed, but a full 3D analysis is carried out to model three dimensional microstructural effects.

Predicting fatigue crack growth life for cold-worked holes based on existing closed-form residual stress models. [PDF]
, 2003 This paper studies the capability of four closed-form solutions for calculating cold expansion-induced residual stresses. The aim is to check whether these models are able to provide accurate solutions of residual stresses for three aerospace grade ...

A three-dimensional model for stage I-crack propagation [PDF]
, 2019 The propagation of short fatigue cracks is simulated by means of a three-dimensional model. Under loading conditions in the high cycle fatigue regime the growth of these cracks can determine up to 90% of the lifetime of a component.

Improved 3D characterization of in-situ soil desiccation cracking by multi-source data integration
GeodermaDesiccation cracking is a common and natural phenomenon under a drought climate. The geometric and morphologic characteristics of the crack pattern are critical to understanding the response of soil mechanical and hydraulic properties to drought climate.

Derivation of a general three-dimensional crack-propagation law: A generalization of the principle of local symmetry [PDF]
, 1993 We derive a general crack-propagation law for slow brittle cracking, in two and three dimensions, using discrete symmetries, gauge invariance, and gradient expansions. Our derivation provides explicit justification for the ‘‘principle of local symmetry,’’
