FIELD: physics.
SUBSTANCE: test unit skin is exposed to X-rays of specified parameters with registering diffraction pattern on computer screen.Thereafter measuring sample of known, uniformly variable elastic length stresses is exposed to X-rays of the same parameters. Its diffraction pattern is overlapped on that of test unit with measuring sample displaced under X-rays until diffraction patterns match. Then macrostress value is read out at the end face of measuring sample by X-ray stain position.
EFFECT: higher accuracy and speed of elastic macrostress measurement directly in standard units.
