Develop understanding of the methods of experimental mechanics and applications
in engineering design and analysis.
Experimental Mechanics: Quantitative observation of the response of
an object or objects to stimuli such as forces.
In all cases, emphasis will be placed on the physics which undergird
the various techniques studied and also on basic laboratory implementation.
Questions to be answered for each technique:
- attributes of the technique - what is it good for
- how does it work
- why does it work
- typical laboratory setups
- what data are obtained
- how interpret results
Topic App. class hrs.
resistance strain gages and transducers 8
basic optics 3
geometric moire 3
optics (diffraction) 2
basic moire interferometry (option) 3
holography and holointerferometry 5
speckle methods 5
motion measurement and accelerometers 4
Laboratories will be a mixture of demonstrations, simple experiments, and
take-home exercises related to laboratory applications of the methods studied.
An additional hour per week, to be scheduled, will be required most weeks for these
demonstrations. Required laboratory exercises will be arranged to suit your schedules.
Required laboratory exercises include:
- application of strain gage and testing of installation, comparison wth
- fabrication and calibration of strain gage transducer
- basic photoelasticity
- response of structure using accelerometers
Demonstrations in classroom and in lab include, among others:
- strain rosettes
- speckle photography
- classical interferometry (Newton, Young, Michelson)
- diffraction phenomena
- digital speckle interferometry
- holographic interferometry
- modal analysis
- wave propagation speed using rsg's
- vibrational strain measurement
- digital data acquisition
Offered as an option for extra credit.
