FIELD: measurement technology.
SUBSTANCE: flat sample of round shape is loaded with elastic punch in round rigid matrix in several stages, at each of which the intensity of the stress and the intensity of deformations is determines, and the diagram of actual stresses is made.
EFFECT: accuracy and reliability of the test is increased by determining the deformations and stresses in a wide range of plastic deformations directly based on the experimental data.
