Abstract

In this paper the finite element method is applied to study the problem of moisture and temperature effects on the stability of a general orthotropic cylindrical composite shell panel subjected to axial or in-plane shear loading. The element employed is a 9-node isoparametric shell element. Since the hygrothermal effects on the elastic properties of the matrices and the fibers are very different, the degrading of the matrices and the fibers are very different, the degrading of elastic moduli, the transverse shear effect and the induced initial stress are all considered in the present study. Numerical investigation shows that if the temperature increase from 300°K to 422°K and the moisture concentration is saturated, the buckling load with both the degrading of elastic moduli and transverse shear deformation considered is approximately 12% lower than Snead/Papazoto's result where only the degrading of elastic moduli is considered.
