In this study, the stabilization of thermoelastic unstable postbuckling in cylindrical piezolaminated panels was investigated by applying piezoelectric actuation. In order to derive the finite element equations of motion of the active piezolaminated cylindrical panels, the total Lagrangian formulation was derived using the Hamilton’s virtual work principles for largely deformed structures with small strain. For the purpose of finding the load-displacement tracking, a cylindrical arc-length method was applied to the iterative Newton-Raphson scheme. Present results show that the eccentric piezoelectric patch can passively remove the unstable postbuckling and the snap-through without piezoelectric actuation. Also, the thermoelastic snap-through can be successfully suppressed by using a piezoelectric actuation.
