Modeling the interaction of a beam of elastic vibrations with the surface of an object under acoustic non-destructive testing

Physical and mathematical models are developed that describe the refraction by a concave cylindrical surface of a field of an elastic transverse wave arbitrarily incident on a surface from a liquid. Immersion control of a small-diameter pipeline is considered. Keywords acoustics, ultrasound, immersion control, physical and mathematical model, bent surface, small-diameter pipeline.
