Cleavage cracking of ductile-metal substrates induced by brittle coating fracture
(Journal article; Peer reviewed, 2018)Brittle coatings are often used to protect underlying ductile substrates from damage. Recent experimental observations show that the fracture of a brittle coating can cause the micro-cracking of the ductile metal substrates, ... -
Effect of Hydrogen on the Collective Behavior of Dislocations in the Case of Nanoindentation
(Journal article, 2018)Most of the studies reported treats the effect of hydrogen on single dislocation line, while models that describe the collective interaction are missing. In this study, hydrogen-induced softening of metallic materials is ... -
Electron-irradiation-induced reinforcement of reduced graphene oxide papers
(Journal article; Peer reviewed, 2013)Here we show that the graphene sheets in reduced graphene oxide papers (rGOPs) can be cross-linked by electron-irradiation-induced sp3 carbon atoms, resulting in significant enhancements in both the mechanical and electrical ... -
High temperature brittle film adhesion measured from annealing-induced circular blisters
(Journal article; Peer reviewed, 2017)Testing high temperature brittle film adhesion is necessary for understanding interfacial failure at elevated temperatures. However, current brittle film adhesion measurement methods are limited to room temperature. ... -
Hydrogen-enhanced grain boundary vacancy stockpiling causes transgranular to intergranular fracture transition
(Journal article; Peer reviewed, 2022)The attention to hydrogen embrittlement (HE) has been intensified recently in the light of hydrogen as a carbon-free energy carrier. Despite worldwide research, the multifaceted HE mechanism remains a matter of debate. ... -
Multiaxial stress–strain response and displacive transformations in NiTi alloy from first principles
(Journal article; Peer reviewed, 2016)Present ab initio study was focussed on a response of NiTi martensite to a superposition of shear and tensile or compressive stresses acting normally to the shear planes. The theoretically predicted base-centered orthorhombic ...
