Abstract

The experimental results on the application of the dynamic speckle-interferometry technique in studies of micro-and macroprocesses occurring in high-cycle fatigue of metals and in live cell are presented. A brief theory of the method and its metrological characteristics are described. The process of the surface alteration in macrocrack initiation was studied using a Charpy-notched sample. It was shown that the processes of the crack formation at the notch tip and the tightening formation at some distance from the tip are simultaneous from the very test start. The secondary plasticity zone emerges after the crack initiation. The reaction of cells to ECHO11 virus was studied on a monolayer of cultured RD cells. It was shown that there is a substantial difference in the dynamics of the speckle images of the cells infected with ECHO11 virus and herpes simplex virus type 1.
