Numerical Simulation of the Thermodependant Viscohyperelastic Behavior of Polyethylene Terephthalate Near the Glass Transition Temperature: Prediction of the Self-Heating During Biaxial Tension Test [PDF]

, 2013
The poly ethylene terephthalate near the glass transition temperature highlights a strongly non linear elastic and viscous behaviour when biaxially stretched at high strain rates representative of the injection stretch blow moulding process. A non linear

Strain rate dependency and fragmentation pattern of expanding warheads

Defence Technology, 2015
For the characterization of the behaviors of a metal material in events like expanding warheads, it is necessary to know its strength and ductility at high strain rates, around 104–105/s.

Measuring the effect of residual stress on the machined subsurface of Inconel 718 by nanoindentation.

PLoS ONE, 2021
Inconel 718 alloy is widely used in aero-engines and high-temperature environments. However, residual stress caused by processing and molding leads to an uneven distribution of internal pressure, which reduces the reliability of service process ...
