Will Compression Affect Temperature and Resonance Frequencies?

AI Thread Summary
Compressing a cylindrical piece of material with high yield strength in a vice can lead to a slight increase in temperature due to elastic compression, as indicated by a Maxwell relation. While the shape of the material does not affect its maximum yield strength, it influences the loading required to reach that yield point. Variations in tension or compression will alter the material's resonance frequencies. The discussion also highlights the need for further reference on the relationship between compression and resonance frequencies. Understanding these effects is crucial in material science and engineering applications.

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?
 
Science news on Phys.org
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.

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
