Piezoelectric strain rate and frequency of applied voltage

[gm3]

If one were to apply, for example, 60 Hz AC to a piezoelectric material, would the strain rate be 60 Hz?

I am not entirely sure if I am using "strain rate" in its proper sense; I use it merely to describe what I imagine would be the rate at which the material expands and contracts while exposed to an AC source.

I assume there is some lag, depending on the material properties... I.e. 60 Hz AC applied would lead to the piezo oscillating at slightly less than 60 Hz. However, I cannot find any information on this and have a very limited knowledge of piezoelectrics.

Edit: I forgot to ask: If one were to apply a voltage to a piezoelectric momentarily and then remove the source, at what rate would the piezo return to its natural geometry?

Any help would be much appreciated!

when the responding frequency is fixed, the delay applies to the phase. A rate is a proportion of a distortion in size in % and depends on the apllied frequency. The biggest distortion is on the resonance frequency of the piezo. Data are provided by the manufacturer.

The piezo returns fully to the initial dimension
