Abstract:
In this work, variation of piezoelectric strain coe cient and permittivity with
change in electric eld is included in constitutive equations of piezoelectricity and used for developing nite element model of a plate instrumented
with piezoelectric patches. Simulation results show that nodal displacement
response and sensor voltage is less controlled if variation of piezoelectric strain
coe cient and permittivity with change in electric eld is not included in
nite element modelling as compared to the case in which these variations
are included in nite element modeling. An experiment is performed so as to
validate simulation results.
