Main Question or Discussion Point

Hi

I am very confused at determining the type of elastic wave in a vibrating body. For example, an elastic solid is flexuraly vibrating in one of its resonant mode. There should be elastic wave excited from this vibration. But, my question is which wave will be excited through it, compressional or shear wave? Please someone explain the wavepropagation phenomena in vibrating solid.

Thanks.

A pressure wave will not result in a flexing sideways movement. It must therefore be a shear wave.

Both types of wave may be present. You may not have noticed the P wave. The speed of propagation of P and S waves are often different so it may be resonant for one but not the other.
