Shear Strength of Beryllium, Uranium, and Tungsten as a Function of Strain, Strain Rate, and Pressure

Abstract

The shear strengths of beryllium, uranium, and tungsten were measured at strain rates of 3.5 × 10−5, 3.6 × 10−3, and 3.7 × 10−1 sec−1. The measurements were taken under nearly hydrostatic pressures of 21, 44, and 63 × 108 N/m2. The shear strength versus shear strain curves are presented along with the pressure and in strain rate derivatives of the experimental parameters.

“…Pa 5:19 Â 10 8 [7] obtained using the semi-analytical method for a shear plane angle of 408. It can be seen that there is very good agreement between both methods at the end of the shear plane heating.…”
