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.
