Micro- and Nano-Indentation of a Hydroxyapatite-Carbon Nanotube Composite
Journal of Nanoscience and Nanotechnology, 2008The mechanical properties of pure synthetic hydroxyapatite and hydroxyapatite-carbon nanotube composites were examined. Vickers microhardness and nanoindentation using a Berkovich tipped indenter were used to determine the hardness, fracture toughness and Young's modulus of the pure hydroxyapatite matrix and the composite materials.

Mechanical Characterization of KMPR by Nano‐Indentation for MEMS Applications
Strain, 2007Abstract: The elastic modulus and hardness of a novel negative photoresist, KMPR, under different heat treatment temperatures, have been characterized in this work using a combination of nanoindentation, uniaxial tension and vibration tests. There are two major conclusions. First, the material exhibits strong anisotropy.

NANO-INDENTATION USING SPHERICAL INDENTERS
Nondestructive Testing and Evaluation, 2001Abstract Depth sensing nano-indentation can be used to determine the mechanical properties of materials in situations where conventional test methods may be difficult or inappropriate to apply. Experimental materials may only be available in small quantities, as a component in a composite or as a coating on a dissimilar substrate.

Fracture toughness in shales using nano-indentation
Journal of Petroleum Science and Engineering, 2020Abstract Fracture toughness property is often ignored but has a significant impact on the hydraulic fracture design, i.e. length and height. It represents the resistance of the rock to hydraulic fracturing and is a direct indicator of rock fracability.

Nano-Indentation Testing and Modelling of Cement Paste
CONCREEP 10, 2015Nano-indentation is used to study the mechanical properties of cement paste. A method is developed to prepare small cement paste cubes (100 µm). These samples are loaded to failure with a Berkovich indenter to obtain the global mechanical properties of the material.

A reply to “comments on ‘a model for nano-indentation creep’”
Scripta Metallurgica et Materialia, 1995Several points are raised as to the validity of the claims of F. Yang and J.C.M. Li that the authors' proposed model for nano-indentation creep was incomplete and produced incorrect ...

Multiscale Simulation of the Size Effect of Nano-Indentation
Key Engineering Materials, 2012In this paper, the size effect of copper, aluminum and silver nanoindentation has been studied by adopting the new multiscale method. According to the analysis and comparison of load-displacement cures for the three materials under the four specimens, the effects of various physical parameters on the dislocation nucleation have been discussed.

In Situ NANO-Indentation of Round Window Membrane
2016The round window membrane (RWM) is the terminal boundary between the fluid-filled inner ear and air-filled middle ear where the sound wave is released from the inner ear after exciting the neuronal sound transducers in the basilar membrane. For the treatment of inner ear diseases, the RWM is an attractive entrance to introduce therapeutic reagents by ...
