摘要

The effect of speckle displacement in the region of the image of a rotating plane specimen revealed earlier is applied to studying rotation of objects under deformation. In the experiment a cylindric specimen is tensioned up to fracture. The total rotation of the surface of a specimen under plastic deformation, which is measured by speckle displacement, and the slope of the surface measured by a photograph of the fractured specimen are shown to coincide to within the measurement errors. The displacements are shown to appear in plastic deformation, to be symmetric about the center of the image of the working part of the specimen and to have opposite directions.
