Will Compression Affect Temperature and Resonance Frequencies?

[EEstudentNAU]

If say a cylindrical piece of material with a high yield strength is compressed in a vice with a force approaching the yield strength, will the temperature be affected? What about its resonance frequencies? Does shape affect the maximum yield strength?

 

[Mapes]

If the material expands when heated, the temperature will increase (slightly) during elastic compression (this can be shown via a Maxwell relation). Shape does not affect the yield strength of the material, but it will affect the loading required to achieve yield. Not sure about the resonant frequencies...

If you vary the tension or compression you will alter the resonance frequency. I used to have a paper on this effect but can remember off the top of my head. I'll take a look for it to provide you a reference.
