Abstract

The in-place displacement of a plate was taken as field variable besides the plate’s deflection and shear strain.By using the spline meshless method,a new dynamic analysis model for thick/thin piezoelectric functionally graded material(FGM) plates under thermal environment was established.Considering FGM physical parameters variation with temperature and in-plane force caused by different temperatures,the effects of in-plate displacement and in-plane force on the dynamic property and dynamic response of the FGM plate were investigated under different boundaries and gradients.Analysis results showed that the new model has the universality and effectiveness for dynamic analysis of thick/thin piezoelectric FGM plates,and has advantages of high efficiency,high precision and no shear locking problems.
