Graphene enhances piezoelectric matrix properties due to its exceptional conductivity and physical characteristics. However, existing models encounter significant challenges in analyzing buckling behavior of graphene-reinforced composite piezoelectric (GRCP) actuators. Inaccuracy in describing transverse shear deformations impact plate stability, particularly due to the disparities in material properties at the interfaces. A new plate model is proposed, featuring a refined interlaminar shear stress field for accurate modeling. Validity is confirmed via 3D elasticity solutions and alternative theories. Compared to existing models, the proposed theory shows superior precision. Additionally, a parametric study explores key factors influencing buckling behaviors of piezoelectric composite plates.
