Nanoindentation studies of materials
have recognized that surface contacts between materials are highly dependent on their mechanical properties1,2. Many different indentation and impression tests have been developed in an effort to measure such mechanical properties from a contact of known geometry. In the past two decades, however, a veritable revolution has occurred in indentation testing, owing to the development of new sensor...
متن کاملRaman Spectroscopic Studies of Bioactive Materials
Bioactive materials including glass and glass-ceramics are nowadays used as medical implants for orthopedic applications. In this study several samples of glass-ceramics have been prepared using both heat treatment and sol-gel processes. The structure and bioactivity of these samples based on their interaction with simulated body fluid (SBF) have been determined. In-vitor, using the Raman s...
متن کاملCharacterization of Viscoelastic Properties of Polymeric Materials through Nanoindentation
Nanoindentation is used to determine the dynamic viscoelastic properties of six polymer materials. It is shown that varying the harmonic frequency of the nanoindentation does not have any significant effect on the measured storage and loss moduli of the polymers. Agreement is found between these results and data from DMA testing of the same materials. Varying the harmonic amplitude of the nanoi...
متن کاملFEATURE Nanomechanical Characterization of Materials by Nanoindentation Series
I nstrumented indentation testing (IIT) is a technique for measuring the mechanical properties of materials. It is a development of traditional hardness tests such as Brinell, Rockwell, Vickers, and Knoop. IIT is similar to traditional hardness testing in that a hard indenter, usually diamond, is pressed into contact with the test material. However, traditional hardness testing yields only one ...
متن کاملAdvances in the mechanical characterization of soft materials by nanoindentation
The emergence of nanoscience has spurred the demand for technologies capable of probing physical phenomena at resolutions down to the atomic length scale. Under this initiative, recent advances in instrumented nanoindentation have made the atomic force microscope and the depth-sensing nanoindenter practical tools in studying the local material properties of a broad array of solid surfaces at mi...
