METHOD FOR NONDESTRUCTIVE TESTING OF A TESTING BODY HAVING AT LEAST ONE ACOUSTICALLY ANISOTROPIC MATERIAL AREA

摘要

A method is described for nondestructive testing of a test body having at least one acoustically anisotropic material area using ultrasound. The method of the invention includes ascertaining or providing directionally specific sound propagation properties which describe an acoustically anisotropic material area; coupling ultrasonic waves into the acoustically anisotropic material area of the test body; receiving ultrasonic waves reflected from an interior of the test body using ultrasonic transducers; and analyzing ultrasonic signals generated by the ultrasonic transducers so that an analysis is performed which is directionally-selective on a basis of directionally-specific sound propagation properties of the anisotropic material.
