Effects of Crystalline Anisotropy and Indenter Size on Nanoindentation by Multiscale Simulation
Nanoindentation processes in single crystal Ag thin film under different crystallographic orientations and various indenter widths are simulated by the quasicontinuum method. The nanoindentation deformation processes under influences of crystalline anisotropy and indenter size are investigated about hardness, load distribution, critical load for first dislocation emission and strain energy unde...
متن کاملInfluence of graphene oxide on flexural strength, modulus of elasticity and micro hardness of poly ethyl methacrylate
Background and Aim: graphene is a two-dimensional nanostructure consist of a single layer of SP2 carbon atoms that arranged by covalent bonds in a hexagonal bee web. The reinforcement by GO is due to functional groups that lead to strong interaction, dispersion and stress distribution. Due to lower mechanical properties and strength of PEMA than PMMA, we evaluate effect of GO on mechanical prop...
متن کاملAtomic analysis and knoop hardness measurement of the cavity floor prepared by Er,Cr:YSGG laser irradiation in vitro.
In the present study, the compositional changes and knoop hardness of the cavity floor prepared by Er,Cr:YSGG laser irradiation was compared with that of the conventional bur cavity. Fifteen laser and 15 bur cavities were cross-sectioned, and subjected to atomic analysis by SEM-EDX and knoop hardness test. Statistical analyses were performed using the Mann-Whitney U-test; a value of P < 0.01 wa...
متن کاملEffect of the increase of energy density on Knoop hardness of dental composites light-cured by conventional QTH, LED and xenon plasma arc.
The aim of this study was to evaluate the effect of the increase of energy density on Knoop hardness of Z250 and Esthet-X composite resins. Cylindrical cavities (3 mm in diameter X 3 mm in depth) were prepared on the buccal surface of 144 bovine incisors. The composite resins were bulk-inserted and polymerized using different light-curing units and times: conventional QTH (quartz-tungsten-halog...
