Fracture toughness and fatigue crack growth characteristics of nanotwinned copper
TL;DR: In this article, the effect of twin density on the crack initiation toughness and stable fatigue crack propagation characteristics of nano twinned copper (NT Cu) was investigated, and the effects of tailored density of nanotwins, incorporated into a fixed grain size of ultrafine-grained (UFG) copper with an average grain size, on the onset and progression of subcritical fracture under quasi-static and cyclic loading at room temperature.

Fracture toughness testing of nanocrystalline alumina and fused quartz using chevron-notched microbeams
Martin Guillermo Mueller,Václav Pejchal,Goran Žagar,Aparna Singh,Marco Cantoni,Andreas Mortensen +5 more
TL;DR: In this article, chevron-notched samples are used to measure fracture toughness in micron-scale samples of brittle materials and use the method to characterize quartz and nanocrystalline alumina.

Flexural strength enhancement in carbon-fiber epoxy composites through graphene nano-platelets coating on fibers
TL;DR: In this article, the desizing and oxidation treatment of carbon fibers and the coating of graphene nano-platelets (GNPs) on the carbon-fibers has been done with an aim to strengthen the interface/interphase between the fiber and the matrix.

Toughness dependence of nano-bainite on phase fraction and morphology
Avanish Kumar,Aparna Singh +1 more
TL;DR: In this paper, the authors investigated the effect of content, size and morphology of constituent phases when austempered at 250, 300, and 350°C and found that the fracture surface showed quasi-cleavage fracture for all the conditions.

Deformation, structural changes and damage evolution in nanotwinned copper under repeated frictional contact sliding
TL;DR: In this article, the effects of twin density and number of repetitions of sliding cycles on the evolution of friction and material pile-up around the diamond indenter were studied quantitatively by depth-sensing instrumented frictional sliding.
