Internationally recognized experts in the field of holographic interferometric testing, X-ray testing, and structural analysis by finite element techniques have come together in ESPRIT project 898 to develop a system that integrates these techniques. This system acts as an external interface between the complementary nondestructive testing methods and computer based structural analysis. In the book the testing and analysis techniques are presented and compared with special emphasis on problems regarding their combination and integration. The architecture and the components of the interface system are described. Experiments proving the feasibility and applicability of the concepts are presented. The chapters of the book dealing with the different techniques are written by the individual partners of the project. A common test object is investigated by all techniques. The book helps the customer to select the testing and analysis method most suitable for his problem. It also presents the background for building up integrated testing equipment for analysis and control.
