Effect of stress relaxation on accelerated physical aging of hydrogenated nitrile butadiene rubber using time-temperature-strain superposition principle

Advanced Industrial and Engineering Polymer Research, 2019
While the stress relaxation is a common phenomenon for polymers, its effect on the stress/strain accelerated aging of the hydrogenated nitrile butadiene rubber (HNBR) cannot be ignored.

Study on Mechanical Relaxations of 7075 (Al–Zn–Mg) and 2024 (Al–Cu–Mg) Alloys by Application of the Time-Temperature Superposition Principle [PDF]

Advances in Materials Science and Engineering, 2017
The viscoelastic response of commercial Al–Zn–Mg and Al–Cu–Mg alloys was measured with a dynamic-mechanical analyzer (DMA) as a function of the temperature (from 30 to 425°C) and the loading frequency (from 0.01 to 150 Hz).

Study of the temperature-humidity equivalence and the time-temperature superposition principle in the finite-strain response of polyamide-6 and short glass fibre-reinforced polyamide-6

Polymer Testing
Polyamide-6 (PA6) and short glass fibre-reinforced PA6 (GPA6) are increasingly used in structural automotive parts exposed to harsh conditions, respectively as liner in Type IV hydrogen tanks and under-the-hood components near the engine.

Time-temperature superposition in viscoelasticity and viscoplasticity for thermoplastics

Polymer Testing, 2021
The use of thermoplastics in the automotive industry is continuously increasing. Design of parts require the characterization and numerical modelling of thermo-mechanical behaviour of those materials under wide strain rate (0–300 s−1) and temperature ...

A Systematical Rheological Study of Maize Kernel

Foods, 2023
In this study, the rheological behavior of maize kernel was systematically investigated using a dynamic mechanical analyzer. The loss in toughness caused by drying resulted in a downward shift in the relaxation curve and an upward shift in the creep ...

Formulation of non-linear viscoelastic–viscoplastic constitutive equation for polyamide 6 resin

Heliyon, 2021
In this study, a non-linear viscoelastic–viscoplastic constitutive equation for polyamide 6 (PA6) is formulated and a new model is suggested for the viscoplastic part of the equation.

Transient 2D Junction Temperature Distribution Measurement by Short Pulse Driving and Gated Integration with Ordinary CCD Camera

Sensors, 2022
The time resolution of the transient process is usually limited by the minimum exposure time of the high-speed camera. In this work, we proposed a method that can achieve nanosecond temporal resolution with an ordinary CCD camera by driving the LED under
