A fatigue multi-site cracks model using coalescence, short and long crack growth laws, for anodized aluminum alloys [PDF]
, 2010 It has been shown that decrease of the fatigue life of aluminium alloys treated with anodization can be explained by the degradation of surface condition due to pickling.

Quasi-static crack propagation by Griffith's criterion [PDF]
, 2008 We consider the propagation of a crack in a brittle material along a prescribed crack path and define a quasi-static evolution by means of stationary points of the free energy. We show that this evolution satisfies Griffith's criterion in a suitable form

Effects of graphite nodules on crack growth behaviour of austempered ductile iron [PDF]
, 2007 Austempered ductile iron (ADI) is a candidate material for camshafts, where however, the early stages of fatigue damage are of major concern during service.

A discrete dislocation dynamics study aiming at understanding fatigue crack initiation [PDF]
, 2003 We use discrete dislocation dynamics to build a model for fatigue crack initiation in a surface grain. Dislocations are modeled as line singularities in an elastic medium where they can be generated from pre-existing sources, glide or annihilate.

Study on crack initiation scratching depth of monocrystalline silicon
Jin'gangshi yu moliao moju gongcheng, 2021 As a typical brittle material, the key to achieve the plastic domain processing of monocrystalline silicon is to make the cutting depth less than the crack initiation cutting depth.

Nihon Kikai Gakkai ronbunshu, 2017 The initiation and growth of internal small fatigue cracks with around ten or several dozen μm in Ti-6Al-4V were nondestructively examined by using synchrotron radiation μCT at the large synchrotron radiation facility SPring-8.

Journal of Rock Mechanics and Geotechnical Engineering, 2023 Crack initiation stress and crack damage stress are two critical indices for assessing the fracture strength of rock mass. However, understanding the stress characteristics of crack initiation and damage under triaxial compression remains still immature.

Influence of woven ply degradation on fatigue crack growth in thin notched composites under tensile loading [PDF]
, 2010 This paper deals with the fatigue of the through the-thickness crack propagation in thin notched composite laminates made of two glass woven plies. It highlights the different crack growths between warp and weft directions of the woven ply.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
