Abstract

Non-destructive methods of material characterization are investigated, by introducing the current specialized sensors and methods employed in the material characterization, evaluation and testing. Detections of defects in materials and components in the manufacturing industries, such as; micro-cracks in aircraft parts, fuselage, jet engine blades, and other components are done by non-destructive techniques. Embedded and leave-in-place sensors can detect micro-cracks and other defects such as de-lamination in materials, in real time, so that the failure in materials can be predicted and prevented. These non-destructive evaluations are done regularly, to predict failure of materials, such as in the bridges other edifices. During the first part of the seminar fundamental principle of the non-destructive evaluation of materials and some examples of applications of the technique employed in evaluation of material strength and thickness will be presented. In the second part the importance of the Fourteenth Annual Symposium on Undergraduate Research and an example of a research project on the subject of non-destructive evaluation done by a former VSU pre-engineering student will be presented.
