New instrumentation and analysis methodology for nano-impact testing

open access: yesMaterials & Design, 2020
The nano-impact test is a technique for high strain rate mechanical characterization of materials at the nano/microscale. However, its use has been limited so far due to the lack of appropriate methods to determine the dynamic hardness under impact ...

Recovery Mechanisms in a Compressed Ni-Ti Superelastic Alloy [PDF]

open access: yesMaterials Research, 2017
The present work studied the influence of annealing on a Ni-Ti alloy submitted to uniaxial compression. The stress-strain curve under compression showed the absence of the Stress-Induced-Martensite (SIM) plateau and 42% of remaining austenitic phase (B2).

Impact Indentation of Metals at the Small Elastoplastic Strain

open access: yesМеханика машин, механизмов и материалов, 2022
The aim of this paper is to study and describe the behavior features of metals under impact loading in the area of elastic-plastic transition, with strains not exceeding 3–4 %, which are typical for measuring the hardness of materials during dynamic ...

An Investigation of Regional Plantar Soft Tissue Hardness and Its Potential Correlation with Plantar Pressure Distribution in Healthy Adults

open access: yesApplied Bionics and Biomechanics, 2021
Background. The plantar soft tissue plays a critical role in absorbing shocks and attenuating excessive stresses during walking. Plantar soft tissue property and plantar pressure are critical information for footwear design and clinical assessment.

Pulse wave response characteristics for thickness and hardness of the cover layer in pulse sensors to measure radial artery pulse

open access: yesBioMedical Engineering OnLine, 2018
Background Piezo-resistive pressure sensors are widely used for measuring pulse waves of the radial artery. Pulse sensors are generally fabricated with a cover layer because pressure sensors without a cover layer are fragile when they come into direct ...

Microscopic dynamics of thin hard rods [PDF]

open access: yesThe Journal of Chemical Physics, 2006
We analyze the microscopic dynamics and transport properties of a gas of thin hard rods. Based on the collision rules for hard needles we derive a hydrodynamic equation that determines the coupled translational and rotational dynamics of a tagged thin rod in an ensemble of identical rods.
