Nondestructive Analysis of Structure and Stresses by Ultrasonic and Micromagnetic Methods

  • P. Höller

Abstract

The objective of materials testing is to assess fitness for purpose. This holds for any type of materials testing: the classical testing for strength, toughness, and other properties by applying load, the structure analysis by using different types of microscopes or diffractometers and also for nondestructive testing which traditionally is devoted to detection and characterization of defects, especially cracklike ones. Assessment also is necessary for safety. Layout, design and fabrication of machinery and components primarily consider purpose and function but as a conditio sine qua non safety must be guaranteed. This means that the envelope of requests for fitness, purpose, function and safety is the basis for layout, design and fabrication.
