Interfacial adhesion of laser clad functionally graded materials [PDF]
, 2003 Specially designed samples of laser clad AlSi40 functionally graded materials (FGM) are made for evaluating the interfacial adhesion. To obtain the interfacial bond strength notches are made right at the interface of the FGMs.

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.

Temperature and load-ratio dependent fatigue-crack growth in the CrMnFeCoNi high-entropy alloy [PDF]
, 2019 Multiple-principal element alloys known as high-entropy alloys have rapidly been gaining attention for the vast variety of compositions and potential combinations of properties that remain to be explored. Of these alloys, one of the earliest, the ‘Cantor

Dynamic interaction of cracks in piezoelectric and anisotropic solids: A non-hypersingular BIEM approach [PDF]
, 2008 A non-hypersingular traction boundary integral equation method (BIEM) is proposed for the treatment of crack systems in piezoelectric or anisotropic plane domains loaded by time-harmonic waves. The solution is based on the frequency dependent fundamental

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.

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 ...

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.
