ME 409 - Experimental Stress Analysis

2 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 gage measurements and analysis, design of strain gage based transducers, photoelasticity and stress analysis. (prereq: ME 309 )
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
• understand concept of stress and strain
• understand underlying principles in using strain gages
• mount strain gages, take measurements and analyze the obtained data
• design strain gage-based transducers for measuring specific loads
• understand basic principles of photoelasticity, and use it as an analysis tool
• use sources outside the class notes and text
