Paper Abstract

Speckle method of determination of relative displacement of two object areas as well as method of studying of micro relief dynamics has been applied for determination of non- reversible deformations of the cylindrical samples under tension. The technology allowing to register in real-time the picture of interference of two speckle non-homogeneous waves and the picture of speckle dynamics has been described. The 2D interference pictures and pictures of speckle dynamics have been presented. The results of studying of dynamics of transverse deformations and results of determination of localization area length of non- reversible deformations up to fracture of the samples have been reported.
