Ultrasonic Methods in Evaluation of Inhomogeneous Materials

The purpose of the School, the content of which is reflected in this book, is to bring together experiences and knowledge of those acousticians who are particularly sensible to materials and their properties, specifically to those materials that may be called inhomo­ geneous. The two things together: acoustics and inhomogeneity, define factually a dimension­ less parameter, AI a, which is the rati...
