Brief: An aircraft manufacturer has asked a consulting engineer (you) to prepare a short report on experimental stress

analysis techniques that could be used for design, testing, or in-service monitoring of structural components. They are

particularly interested in the electrical resistance strain gauge and digital image correlation methods.

Prepare a short report for the company which covers both electrical resistance strain gauging and digital image

correlation for use in experimental stress analysis. The report should briefly introduce experimental stress analysis and

its relevance, introduce strain gauges and digital image correlation methods and give relevant background to each. You

should then cover the fundamental concepts and mode of operation (how it works!) associated with each technique and

give guidance for obtaining accurate measurements. Finally, critically compare the methods, give suitable applications

for each technique in aircraft engineering and offer conclusions and recommendations to the aerospace company using

the information you have gathered as evidence.
