Abstract
The article presents a combined experimental and theoretical method of determining strength characteristics of materials in high-speed tensile tests on specimens with shortened gauge length in which there is no region of uniaxial state of stress. Numerically, by the finite element method, zones of nonuniaxial state of stress over the gauge length of the specimen are established.
