Local mechanical properties by Atomic Force Microscopy nanoindentations [PDF]

, 2008
The analysis of mechanical properties on a nanometer scale is a useful tool for combining information concerning texture organization obtained by microscopy with the properties of individual components- Moreover, this technique promotes the understanding

Caracterización nanomecánica de la estructura celular y anatómica de Eucalyptus nitens y su relación con la frecuencia de grietas y rajaduras en madera redonda Characterization nanomechanics of wood cell structure and anatomy in Eucalyptus nitens and its relation to the cracking and fractures in round wood

Maderas: Ciencia y Tecnología, 2012
El objetivo de este trabajo fue localizar el mínimo volumen en árboles de E. nitens que caracterice el comportamiento mecánico y anatómico para un muestreo no destructivo. Los árboles fueron cortados desde Mulchén y Yungay en la región del Bío-Bío.

Nanoindentation of Soft Biological Materials [PDF]

Micromachines, 2018
Nanoindentation techniques, with high spatial resolution and force sensitivity, have recently been moved into the center of the spotlight for measuring the mechanical properties of biomaterials, especially bridging the scales from the molecular via the cellular and tissue all the way to the organ level, whereas characterizing soft biomaterials ...

Linking structure and mechanical properties via instrumented nanoindentations on well-defined morphology poly(ethylene) Polymer 50 8 1939-1947 2009 [PDF]

, 2009
Several poly(ethylene) samples with a broad range of morphologies were studied in this work using nanoindentations. The samples had degrees of crystallinity ranging from 30 to100% while their Young’s modulus ranged from few tens of MPa up to several GPa.

Nanoindentation of human meniscal surfaces [PDF]

Journal of Biomechanics, 2012
Menisci are crescent shaped fibrocartilaginous structures which support load distribution of the knee. The menisci are specifically designed to fit the contour of the femoral condyles, aiding to disperse the stresses on the tibial plateau and in turn safeguarding the underlying articular cartilage.

Contact pressure of porous Al2O3 probed by nanoindentations [PDF]

, 2008
Contact pressure of porous Al2O3 probed by nanoindentation was investigated by dimensional analysis with special attention paid to scaling effects in the mechanical behavior. It was found that, for sample containing small grains and interconnected pores,
