RISThe Effect of Pulse Electric Current on the Mechanical Properties and Fracture Behaviors of Aluminum Alloy AA5754
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influences of pulse electric currents at energy density levels of 0.105 J/mm3 and 0.150 J/mm3 on AA5754's flow stress and elongation are investigated. Different combinations of current density and pulse duration ...
Analysis and Observations of Current Density Sensitivity and Thermally Activated Mechanical Behavior in Electrically Assisted Deformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow of electric current through a metal during deformation has been observed to reduce its flow stress and increase its ductility. This observation has motivated the development of advanced “electricallyassisted†...
Nature-Inspired Plate-Based Metamaterials With Negative Poisson's Ratio and Ultrahigh Stiffness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Honeycomb structures, inspired by bee honeycomb, are one of the most efficient engineering materials. They were usually used as 2D honeycomb cores and honeycomb sandwich panels. However, a natural bee honeycomb is a 3D ...
