An Experimental Method For Three-Dimensional Dynamic Stress Analysis, Larry E. Williams
An Experimental Method For Three-Dimensional Dynamic Stress Analysis, Larry E. Williams
Mechanical Engineering ETDs
It is the purpose of this thesis to present an evaluation of a method of experimental dynamic stress analysis utilizing electrical resistance strain gauges located internally. If it can be shown that the proposed experimental procedure is valid, then the transient stress phenomena could be continuously recorded from an internal, integral strain gauge placed at any desired location and in any orientation in a suitable model.

The stress-strain characteristics of a material are a measure of the energy absorption characteristics of that material. Generally, plastics show permanent deformation at low values of strain but will withstand a large amount of strain before reaching their ultimate strength. Therefore, in effect, plastics are good energy absorbing materials. If the packaging designer could predict the effect of variation in strain rate and temperature on the stress-strain characteristics of a given plastic, his designs would be more reliable.
