What is the best way to manage unwanted vibration in the creation of a bat?
Jasus! That is question and a half!!!!
Ok ummmm Cricket Bat willow is a natural fibre reinforced composite!
We know the vessel run through the cricket bat from shoulder to toe. We can see those vessels are layered in the willow itself and mixed with the grain. This longitudinal nature of the willow fibres determine some really important factors in cricket bats. That is, in this vessel orientation and layering we get stiffness.
So what am I talking about, well elasticity and bending frequencies.
Due to the vessel layering it affects those aspects of the cricket bat, this leads to cricket bat performance. I wont go to far into this but here is a snippet. They are both intertwined here, elasticity and bending frequencies.
Ok bending modes of the bat, this is based on the bat shape [profile] and if you take into consideration the excitation range [vibration] of a cricket bat based on impact we know you can raise or lower the bending mode frequencies of a bat based on mass of the blade and handles, in layman terms a gain in performance.
But now you can see the willow itself, the vessel layering and the grain effect this as well and why the pressing of the blade is so important as this adds another composite layer.

So in short pressing, its profile shape and handle choice
pain in the ass hey!
