Abstract
For this article, the thermal buckling and free vibration of Composite Sandwich Curved Panels (CSCP) in a thermal environment are analyzed. To achieve the purposes, Hamilton’s principle is used to deduce the non-linear vibration differential equations of CSCP based on the first-order discrete layer model. In these equations, non-linear change of lateral and longitudinal displacements are taken into account because of the temperature change. Later, these equations are solved by the Navier method and are authenticated by comparison with finite element simulation results. At last, the influence rules of structural parameters on Critical Buckling Temperature (CBT) of CSCP are studied and exhibited vividly. Meanwhile, some new results about thermal buckling and free vibration of CSCP are presented for the first time.
