The effects of piezoeletric on buckling behavior of composite cylinders

Abstract

In this study a composite cylindrical shell is loaded under a steady-state axisymmetric voltage and analyzed using a semi-analytical finite element method. An attempt has been made to define a critical buckling voltage for a single layer cylindrical composite shell under a clamped-clamped boundary condition at different fiber orientation and length to radius ratios. The voltage to cause instability is derived from fundamental equations of the piezoelectric constitutive relations. Critical buckling voltage applied to a cylindrical composite shell can be determined by employing a piezoelectric actuator.
