Using measurements and testing to support FE-analyses of welded structures exposed to fatigue

Product development is becoming increasingly more complex. Therefore, during the years, the mechanical designer´s profession has been split into several fields, each having specialized engineers. Three such professionals are the Calculation Engineer, the Measurement Engineer, and the Test Engineer. This handbook is written to help these different professionals to better understand each other and to show ways how to use each other´s skills and knowledge, methods, and equipment in the most effective way. The payback in lighter, more durable and at the same time more cost-efficient structures is huge. One main subject in this handbook is how to translate measured data into usable input for theoretical analyses, and how to find suitable measurement positions. Another main subject is how to perform verifying rig tests, based on measurements and theoretical analyses. Several methods for analyzing, measuring, and testing steel structures subjected to fatigue are presented and discussed.
