Breaking in a cymbal?....It's not a motor.

Wake up and smell the amps!!!

Whoever told you all that stuff is a fool. :idea:

Not really...

When you play a cymbal, it goes through a process called "work hardening" and the crystaline structure of the bronze is actually altered by the stick striking it, so in essence, it does "

*break in*".

Hand Hammering a cymbal is also work hardening it, but since you're hitting it with a hammer instead of a wooden stick, it has a more profound effect. "breaking in" a cymbal happens over a MUCH longer period of time and it is far more subtle than whacking it with a hammer.

For the math junkies out there, There are two common mathematical descriptions of the work hardening phenomenon.

Hollomon's equation is a power law relationship between the stress and the amount of strain.

Ludwik's equation is similar but includes the yield stress,

where

*K *is the strength index and

*n *is the strain hardening index.

If a material has been subjected to prior deformation (at low temperature such as hammering) then the yield stress will be

*increased *by a factor depending on the amount of prior strain.

The constant

*K* is structure dependent and is influenced by processing while

*n *is a material property normally lying in the range 0.2-0.5. The strain hardening index can be described by:

This equation can be evaluated from the slope of a log(σ) - log(ε) plot. Rearraging allows a determination of the rate of strain hardening at a given stress and strain

Any Questions?

Bueler??

Anyone?
