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 gage measurements and analysis, design of strain gage based transducers, photoelasticity and stress analysis. A graduate student presentation or report on a relevant topic is also required. (prereq: graduate standing, 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
