Rheology and ultrasonic properties of Pt57.5Ni5.3Cu14.7P22.5 liquid [PDF]

open access: yes, 2007
The equilibrium and nonequilibrium viscosity and isoconfigurational shear modulus of Pt57.5Ni5.3Cu14.7P22.5 supercooled liquid are evaluated using continuous–strain-rate compression experiments and ultrasonic measurements. By means of a thermodynamically-

Respiration rate and volume measurements using wearable strain sensors. [PDF]

open access: yes, 2019
Current methods for continuous respiration monitoring such as respiratory inductive or optoelectronic plethysmography are limited to clinical or research settings; most wearable systems reported only measures respiration rate.

Timing and rate of global contraction on Mercury

open access: yesGeophysical Research Letters, 2017
Impact bombardment and global contraction due to planetary cooling have both shaped the surface of Mercury over very long time scales. Landforms associated with these processes, i.e., impact craters and thrust fault‐related escarpments, and their mutual ...

Dynamic recrystallization mechanisms and twining evolution during hot deformation of Inconel 718 [PDF]

open access: yes, 2016
The hot deformation behavior of an IN718 superalloy was studied by isothermal compression tests under the deformation temperature range of 950–1100 °C and strain rate range of 0.001–1 s-1 up to true strains of 0.05, 0.2, 0.4 and 0.7.

Experimental study on effect of graded loading rate on creep characteristics of anthracite

open access: yesMeikuang Anquan, 2022
In order to study the effect of graded loading rate on creep characteristics of anthracite, the effects of graded loading rate and stress level on instantaneous strain, creep strain and creep rate of coal samples were analyzed by triaxial creep tests of

Nylon-6/rubber blends: 6. Notched tensile impact testing of nylon-6(ethylene-propylene rubber) blends [PDF]

open access: yes, 1994
The deformation and fracture behaviour of nylon-6/EPR (ethylene-propylene rubber) blends is studied as a function of strain rate and rubber content.

A Novel Electromechanical Apparatus for Intermediate Strain-Rate Testing and Validation on Polycarbonate

open access: yesApplied Sciences
The characterization of material behavior under intermediate deformation rates remains a major challenge, since conventional testing devices are mainly developed for either quasi-static or high strain-rate conditions.

Effect of strain rate on serrated load of indentation in Al-Mg alloy

open access: yesNihon Kikai Gakkai ronbunshu, 2017
Indentation tests are used to determine the local mechanical properties of materials. Previously, the indentation strain rate was correlated with the strain rate in uniaxial tests based on the hardness, which was the obtained load divided by the cross ...
