TL;DR: The procedures and results of indentation tests performed on Matrigel with atomic force microscopy (AFM) in an aqueous, temperature controlled environment are presented and the average modulus value was found to be approximately 450 Pa, considerably higher than macroscopic shear storage moduli reported in the scientific literature.

TL;DR: In this paper, the authors used nanoindentation to evaluate the elastic modulus and hardness properties of the Ti and Ti-TiB composite materials, and showed that the results showed that there is a high degree of consistency between the characterization using nanoinfentation and the wear evaluation from conventional wear tests.
Abstract: Ti and Ti-TiB composite materials were produced by selective laser melting (SLM). Ti showed an α΄ microstructure, whereas the Ti-TiB composite revealed a distribution of needle-like TiB particles across an α-Ti matrix. Hardness (H) and reduced elastic modulus (Er) were investigated by nanoindentation using loads of 2, 5 and 10 mN. The results showed higher H and Er values for the Ti-TiB than Ti due to the hardening and stiffening effects of the TiB reinforcements. On increasing the nanoindentation load, H and Er were decreased. Comparison of the nanoindentation results with those derived from conventional hardness and compression tests indicated that 5 mN is the most suitable nanoindentation load to assess the elastic modulus and hardness properties. The wear resistance of the samples was related to their corresponding H/Er and H3/Er2 ratios obtained by nanoindentation. These investigations showed that there is a high degree of consistency between the characterization using nanoindentation and the wear evaluation from conventional wear tests.

TL;DR: In this paper, a non-linear elasto-viscoplastic model containing various deformation components is proposed, by connecting a Hooke body, a parallel combination of Hooke and plastic slide bodies, a Kelvin body, and a generalized Bingham body.
