摘要：

Effects of moisture and temperature on the free vibration of laminated composite plates are investigated. The analysis is carried out by the finite element method with the quadratic isoparametric element, which takes transverse shear deformation into account. The analysis also accounts for lamina material properties at elevated moisture concentration and temperature. Results are presented showing the reduction in the natural frequency with the increase in uniform moisture concentration and temperature for symmetric and antisymmetric laminates with simply supported and clamped boundary conditions. © 1992.
