Abstract
The article deals with main methods applicable for definition of intense - deformed condition of products special materials. Experimental researches of speed dependence of elastic waves distribution from tension in various samples are conducted and revealed the advantage of laser - ultrasonic diagnostics method realized by means of volume waves, to nondestructive control of mono axial tension in a metal structures. The specified advantages of laser and ultrasonic diagnostics method and the received research results on samples from hot-rolled sheet steel of 08kp 2 mm thick and AK33CB steel of 20 mm thick while stretching tests showed sensitivity not less than 3,5 m/s.
