FIELD: test equipment. ^ SUBSTANCE: a cylindrical shear-test specimen is loaded by torsion, the torque is measured, the torsion angle is presented and the value of the ultimate shear stress is calculated. The torque is measured at an attainment of a homogeneous plastic deformation, which is indicated by a permanent load at torsion. ^ EFFECT: enhanced accuracy of tests. ^ 2 dwg
