How Does the Inverse Piezoelectric Effect Alter Crystal Dimensions?

[kiutukri]

Hi, I'd like to get some help with my homework.
Piezoelectric crystals will change about 0.1% of their static dimension when an external electric field is applied to the material.
1. What happens with the static dimension if the external electric field applied is a constant?
2. Will the static dimension reach a limit?
3. It's always expanding and contracting?

Many thanks in advance.

Then you should post in the homework section and use the template. :)
