These Proceedings comprise 50 papers presented by scientists from Germany, United States. France and Israel, with the majority of papers originating from Germany and the United States. The interest in nondestructive testing (ndt) has increased considerably during recent years leading to the publication of an increasing number of papers treating fundamental aspects as well as practical applications of ndt procedures. The famous ‘needle in the haystack’ is still being looked for, but the demands on the dimensions and the physical qualities of the ‘needle’, that is, the material defects. are still made more rigorous. In spite ofconsiderable research efforts a gap still exists between research in ndt and the state of its practical implementation. The development of new materials, for instance composites, and new material geometries is progressing very fast and these materials possessing inherent inhomogeneous structures and stress fields are more inclined to the formation of material defects. The papers published here are divided into seven chapters, the titles ofwhich reflect the width and the depth of the subjects discussed during the workshop. These chapters are: probes, data acquisition and data preprocessing during ultrasonic testing comprising nine papers; classification and reconstruction of defects by ultrasonic testing comprising 13 papers; forward scattering comprising seven papers; inverse scattering, comprising seven papers; acoustic emission, comprising two

papers: electrical and magnetic methods. theory and applications. comprising six papers and non-destructive stress measurement, comprising six papers. From the first chapter the ALOK-technique (amplitudeshould transit-time-locus-curve) in particular be emphasized as a new system for search and analysis of defects in materials. Among other new methods should also be mentioned imaging using phased arrays. one- and two-dimensional holography and oneand twodimensional synthetic aperture focusing techniques, the last two mentioned methods being combined in the socalled Holosaft method of analysis. Stress measurement treated in the last chapter is a subject of increasing interest in relation to applied as well as to residual stresses. Papers treating birefringence of polarized ultrasonic shear waves, changes of polarization of polarized ultrasonic waves, excitation of ultrasonic waves by magnetostriction. temperature-dependent velocity methods etc are published in chapter 7. The book constitutes an essential publication in its field and it will certainly find its way onto the book shelves in engineering companies as well as in research institutes. The printing and the figures are of the traditional high standard of Springer-Verlag. The price of the book is reasonable seen in the background of the amount of valuable material the book makes available. Only a subject index is missing, which makes the search for specific information somewhat time consuming. Yet, this disadvantage does not overshadow the general outstanding quality of the book. L.
