Concepts and Techniques for Ultrasonic Evaluation of Material Mechanical Properties

  • Alex Vary

Abstract

Reliable performance of advanced, high-strength materials in critical applications depends on assuring that each part placed in service satisfies the conditions assumed in design and life prediction analyses. Reliability assurance requires the availability of nondestructive evaluation (NDE) techniques not only for defect detection but also for verification of mechanical strength and associated properties. Advanced NDE techniques are needed to confirm that metallic, composite, or ceramic parts will not fail under design loads due to inadequate or degraded mechanical strength. This calls for NDE techniques that are sensitive to variations in microstructure, extrinsic properties, and dispersed flaw populations that govern the ultimate mechanical performance of a structure.
