Data Analysis and Correlation with Digital Computers--Nondestructive Testing

Abstract

The purpose of this research was to ascertain feasibility of using digital computers to facilitate nondestructive testing techniques. Energy envelopes were made and were analyzed on the LSU hybrid computer which consists of an EAI 680 for the analog component and a Sigma 5 for the digital component. The sound envelopes were subjected to a filtering program making use of the Fourier analysis in order to arrive at a response frequency. The response frequency for 'good' specimens were compared against the response frequency for faulty specimens. During the course of the investigations nondestructive tests were investigated which included stress analysis, dimensional properties, faulty specimens and faults in long, thin wall tubing.
