A method of determining the stress-strain relation of materials when stresses are applied for times of the order of 20 microseconds is described. The apparatus employed was a modification of the Hopkinson pressure bar, and detonators were used to produce large transient stresses. Thin specimens of rubbers, plastics an…
The complex dielectric constatn of ceramic barium titanate has been measured as a function of temperature from 300\ifmmode^\circ\else\textdegree\fi{}K down to 2.8\ifmmode^\circ\else\textdegree\fi{}K. The large value of the slope of the real part of the dielectric constant, ${K}^{\ensuremath{'}}$, versus temperature cu…
