Scaling, dimensional analysis, and indentation measurements
Yang-Tse Cheng,Che-Min Cheng +1 more
TL;DR: In this article, the authors provide an overview of the basic concepts of scaling and dimensional analysis, followed by a review of some of the recent work on applying these concepts to modeling instrumented indentation measurements.
Journal ArticleDOI
Nanoindentation mapping of the mechanical properties of human molar tooth enamel.
TL;DR: N nanoindentation is used to map out the properties of dental enamel over the axial cross-section of a maxillary second molar, finding that local variations in mechanical characteristics were correlated with changes in chemical content and microstructure across the entire depth and span of a sample.
Journal ArticleDOI
Biological materials: Functional adaptations and bioinspired designs
TL;DR: In this paper, the authors conduct an analysis connecting the structure (nano, micro, meso, and macro) to the mechanical properties important for a specific function, and address how biological systems respond and adapt to external mechanical stimuli.
Journal ArticleDOI
Nanoindentation of biological materials
TL;DR: This work has shown that indentation data analysis can be used to investigate variations in mechanical properties with changes in tissue organization or composition in mineralized and soft tissues, and map mechanical properties spatially in complex biomaterials.
Journal ArticleDOI
Mechanical properties of polymer-infiltrated-ceramic-network materials
TL;DR: SEM observations of the indentation induced cracks indicate that the polymer network causes greater crack deflection than the dense ceramic material, pointing out the correlation between ceramic network density, elastic modulus and hardness of PICNs.

An improved technique for determining hardness and elastic modulus using load and displacement sensing indentation experiments
Warren C. Oliver,George M. Pharr +1 more
TL;DR: In this paper, the authors used a Berkovich indenter to determine hardness and elastic modulus from indentation load-displacement data, and showed that the curve of the curve is not linear, even in the initial stages of the unloading process.

A method for interpreting the data from depth-sensing indentation instruments
M. F. Doerner,William D. Nix +1 more
TL;DR: In this paper, a method for obtaining hardness and Young's modulus from the data obtained from these types of instruments is described, where the elastic displacements are determined from data obtained during unloading of the indentation.

The effect of porosity and mineral content on the Young's modulus of elasticity of compact bone.
TL;DR: The Young's modulus of elasticity, the calcium content and the volume fraction (1-porosity) of 23 tension specimens and 80 bending specimens, taken from compact bone of 18 species of mammal, bird and reptile, were determined.
