摘要：The paper develops geometrically nonlinear finite element (FE) models for macro-fiber composite (MFC) bonded thin-walled smart structures using various nonlinear shell theories based on the Reissner-Mindlin hypothesis. The nonlinear FE model considers arbitrary piezoelectric fiber orientation in MFC patches, which influences the structural response significantly. Two different kinds of MFCs are considered, namely MFC-d(31) and MFC-d(33), in which the former one is dominated by the d(31) effect, while the latter one is by the d(33) effect. The mathematical model is first validated by a cantilevered plate with the simulation and experimental results in the literature. Afterwards, a cantilevered plate and a semicircular shell both bonded with multi-MFC patches are analyzed by the present nonlinear FE model. (C) 2016 Elsevier Ltd. All rights reserved.
