Tg changes? Or do you mean they deflect sooner under more load?
Maybe "load" includes the heat that comes from the changes forces from the vibrations? But even then, that would be additional heat sources, rather than a change in the temperature where it happens.
Polycarbonate shows little change vs pressure [1]:
