Essay

3. It is developed methods of controlling the stress-strain state, the values of elastic constants and the presence of defects. It is developed mathematical model sdescribing the propagation of ultrasonic circumferencial waves. It is developed a method of continuous control of wall thickness of pipelines with irregular surface in the conditions of use bulk ultrasonic waves.
