Abstract
The aim of this paper is to model the one-dimensional behaviour of
a soft PZT tested in compression. Thanks to a viscoplastic formulation,
the effects of cyclical loading and loading rates are also taken into
account. The coupling between remnant strain and polarisation is
achieved through a mechanically induced depolarisation function.
