ME 609 - Experimental Stress Analysis2 lecture hours 2 lab hours 3 credits
Course Description
In this course students learn to apply modern experimental stress analysis techniques to measure strains and stresses in engineering components and structures. The course includes strain gauge measurements and analysis, design of strain gauge-based transducers, photoelasticity and stress analysis. A graduate student presentation or report on a relevant topic is also required. (prereq: ME 309 or equivalent)

- Understand concept of stress and strain
- Understand underlying principles in using strain gauges
- Mount strain gauges, take measurements and analyze the obtained data
- Design strain gauge-based transducers for measuring specific loads
- Understand basic principles of photoelasticity, and use it as an analysis tool
- Sources outside the class notes and text
