A smart laminate model developed using the nonlinear piezoelectric model, i.e.,
electroelastic and electrostrictive effects, and von Kármán type geometric nonlinearity is
proposed. On the basis of the proposed model, the analytical solutions for extensional and
bending deformations of symmetrically constructed piezoelectric laminates under
large electric fields are calculated. A comparison between the present nonlinear
extension deformation of a piezoelectric laminated plate and the induced strain model
shows that more realistic results are obtained with the present model. Numerical
simulation reveals that the calculated results agree well with the experimental
data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
