Strain rate dependent micromechanical properties of NiTi shape memory alloys: Laser powder bed fusion versus casting

open access: yesForces in Mechanics, 2021
As the strain rate influences the loading sensitivity of the metallic materials over time, it is very important to assess the associated plastic behavior exposed to a diverse strain rate.

Depletion of chondrocyte primary cilia reduces the compressive modulus of articular cartilage [PDF]

open access: yes, 2014
Primary cilia are slender, microtubule based structures found in the majority of cell types with one cilium per cell. In articular cartilage, primary cilia are required for chondrocyte mechanotransduction and the development of healthy tissue.

Temperature dependent mechanical property of PZT film: an investigation by nanoindentation.

open access: yesPLoS ONE, 2015
Load-depth curves of an unpoled Lead Zirconate Titanate (PZT) film composite as a function of temperature were measured by nanoindentation technique. Its reduce modulus and hardness were calculated by the typical Oliver-Pharr method.

Evaluation of Young's modulus of skin tissue by indentation test based on modified Hertz contact theory

open access: yesNihon Kikai Gakkai ronbunshu, 2015
An advantage of the indentation test is that it can be used to easily measure the elastic modulus of biological soft tissue in noninvasive. To measure Young's modulus, E*, of skin tissue by an indentation test, we expanded the Hertz contact theory ...

Direct Visualisation of the Depth-Dependent Mechanical Properties of Full-Thickness Articular Cartilage.

open access: yes, 2012
The structural anisotropy of articular cartilage controls its deformation response. As proteoglycans and collagen vary with depth, simple uniaxial compression results in inhomogeneous deformation with distinct depth-dependent mechanical properties ...
