Stress Relaxation Behaviour and Creep Constitutive Equations of SA302Gr.C Low-Alloy Steel

High Temperature Materials and Processes, 2018
In order to study the stress relaxation behaviour of SA302Gr.C low-alloy steel, the stress relaxation experiments were performed at the temperatures of 400, 500 and 620 °C with the constant strain of 0.5 %.

Impact of Textile Architecture on the Electromechanical Behavior of Conductive Carbon: Silicone Composite Strain Sensors

Advanced Engineering Materials, EarlyView.
A stretchable carbon composite is integrated by stencil printing onto two different types of textile, with different yarn morphologies. The impact of the knit structure and coating direction on the performance of the sensor composite is evaluated and used to derive a model estimating nominal resistance at a given strain near the percolation threshold ...

EFFECT OF MISS STITCH ON THE TENSILE STRESS RELAXATIONOF RIB WEFT KNITTED FABRICS [PDF]

Annals of the University of Oradea: Fascicle of Textiles, Leatherwork, 2020
Stress relaxation is a time-dependent mechanical behavior in textiles. Textile deformations occurred as a result of stress relaxation, induces disturbances in textile function, and further disproportion between performance and application.
