Paper Title:
Can Non-Destructive Stress and Microstructure Analysis Support the Fracture Risk Assessment? A Discussion based on the IZFP Experience
  Abstract

Using computer simulations the influence of different standard deviations of the yield strength, ultimate tensile strength and of Kc values on the probability of the crack growth in an Al-alloy pressure vessel is studied. The state of art of non destructive materials characterization as it is achieved at the IZFP is demonstrated by experimental results of non destructive stress analysis, evaluation of strength data and of materials state characterization. The goals of future developments are clear: in case of components made by Al alloys, the combined use of the ultrasonic and eddy current techniques and in case of steel components, the additional use of micro magnetic techniques have to be enforced. The miniaturization of the sensors and the continuation of the experimental investigation of the correlation between the strength and Kc data on one side and the materials structure as characterized by non destructive tools on the other side are the next steps.
