Near-threshold fatigue propagation of physically through-thickness short and long cracks in a low alloy steel [PDF]
, 2014 International audienceIn this paper, the near-threshold fatigue behavior of physically through-thickness short cracks and of long cracks in a low alloy steel is investigated by experiments in ambient air. Physically through-thickness short fatigue cracks

Healing of fatigue crack in epoxy materials with epoxy/mercaptan system via manual infiltration
eXPRESS Polymer Letters, 2010 The present work verified the capability of epoxy/mercaptan/tertiary amine system for retarding and/or arresting fatigue cracks in epoxy materials subjected to cyclic loading at room temperature.

Investigation of Atmospheric Moisture during Heat Treatment of Glass Fibres
Fibers, 2019 The tensile strength of single water-sized E-glass fibres that were thermally conditioned, either in air or under vacuum, was investigated. The vacuum removed water from the conditioning atmosphere, as well as the fibre surfaces, at room temperature but ...

Quasicontinuum simulation of fracture at the atomic scale [PDF]
, 1998 We study the problem of atomic scale fracture using the recently developed quasicontinuum method in which there is a systematic thinning of the atomic-level degrees of freedom in regions where they are not needed.

Crack paths under mixed mode loading [PDF]
, 2008 Long fatigue cracks that initially experience mixed mode displacements usually change direction in response to cyclic elastic stresses. Eventually the cracks tend to orient themselves into a pure mode I condition, but the path that they take can be ...

Self-healing of fatigue crack in epoxy materials with epoxy/mercaptan system
eXPRESS Polymer Letters, 2011 Successful retardation or arrest of fatigue crack is observed in self-healing epoxy composite containing dual encapsulated healant, i.e. two types of microcapsules that respectively include epoxy prepolymer and mercaptan/tertiary amine hardener.

Edge waves and localisation in lattices containing tilted resonators
, 2017 The paper presents the study of waves in a structured geometrically chiral solid. A special attention is given to the analysis of the Bloch-Floquet waves in a doubly periodic high-contrast lattice containing tilted resonators.

The brittleness index in hydraulic fracturing [PDF]
, 2015 We present a new definition of a brittleness index which is used as a criterion for candidate selection of rock intervals for hydraulic fracturing. The new index is a combination of material strength parameters and insitu stresses. It was derived from an

Smart design A2Zr2O7-type high-entropy oxides through lattice-engineering toughening strategy
npj Computational MaterialsThe fracture toughness (KIC) of high-entropy oxides (HEOs) is critically important for several applications, but identification and quantification of the toughening mechanisms resulting from lattice-engineering/distortion in HEOs is challenging.

Pressure wall hole size and maximum tip-to-tip crack length following orbital debris penetration [PDF]
The threat of damage from high speed meteoroid and orbital debris particle impacts has become a significant design consideration in the development and construction of long duration earth-orbiting spacecraft.
