How Is It That SHM Can Break Things?
I Know That Some Materials Have A Frequency At Which They Break, But Why?

Because at the resonant frequency, the amplitude of the deformation can be maximized to the point where stresses exceed the breaking point of the material.
It is NOT just the frequency. The source of the frequency has to have enough power and coupling to the device that is to be broken.
The physical shape and composition of the object will affect how easy it is for the object to be broken by such a method.

It's called their 'resonant frequency' and it's more a function of their shape and size than the materials of which they're built.
Any good Physics book can explain mechanical resonance, or you could go look it up on the 'net.
