Bone indentation test
WebOct 1, 2003 · Validation is achieved by comparing the apparent longitudinal Young's modulus supplied by a traction test of bovine bone microsamples (Sections A and B) with the alternative approach based on the indentation modulus of the bone matrix considering the effect of porosity (Sections B–D). 2. Materials and methods Different techniques are used to quantify material characteristics at smaller scales. Measuring mechanical properties for materials, for instance, of thin films, cannot be done using conventional uniaxial tensile testing. As a result, techniques testing material "hardness" by indenting a material with a very small impression have been developed to attempt to estimate these properties. Hardness measurements quantify the resistance of a material to plastic deformation. Indentatio…
