An Interrupted Dynamic Tensile Testing for Pure Copper Bars
interrupted tension high strain rate constitutive model necking void evolution pure copper bar
2012/9/24
A high-speed tensile fac ility (HSTF) invented by us was applied to interrupt tests for pure copper bars controlled locally at different levels of elongatio n. It was realized to isolate and identify ...
A copper negative index metamaterial in the visible / near-infrared
copper negative index visible near-infrared Optics
2011/8/11
Abstract: We propose a design for a novel plasmonic copper metamaterial with an index of refraction equal to -1 at an operating wavelength of 700 nm. Using numerical simulations, we demonstrate negati...
