The present study deals with the parametric resonance behaviour of laminated composite curved shell panels in a hygrothermal environment using Bolotin's approach. A simple laminated model is developed using first order shear deformation theory (FSDT) for the vibration and dynamic stability analysis of laminated composite shells subjected to hygrothermal conditions. A computer program based on the finite element method (FEM) in a MATLAB environment is developed to perform all necessary computations. Quantitative results are presented to show the effects of curvature, ply-orientations, degree of orthotropy and geometry of laminates on the parametric instability of composite curved shell panels for different temperature and moisture concentrations. The excitation frequencies of laminated composite panels decrease with the increase of temperature and moisture due to reduction of stiffness for all laminates.

“…Many studies, based on classical plate theory, of thin rectangular plates subjected to mechanical or thermal loading or their combinations as well as the hygrothermal effects are available in the literature [Whitney and Ashton 1971;Sai Ram and Sinha 1992]. However, studies of temperature and moisture effects on the bending of rectangular plates based on the shear deformation theories are limited in number, and all these studies assumed perfectly initial configurations [Pipes et al 1976;Yang and Shieh 1987;Sai Ram and Sinha 1991;.…”

“…Therefore, there is a need to understand the behavior of composite structures subjected to hygrothermal conditions. Whitney and Ashton [1971] have used the classical laminate plate theory to study the hygrothermal effects on bending, buckling and vibration of composite laminated plates using the Ritz method and neglecting the transverse shear deformation. Pipes et al [1976] have presented the distribution of in-plane stresses through the thickness of symmetric laminates subjected to moisture absorption and desorption.…”

The static characteristics of an exponentially inhomogeneous plate under a transverse uniform loading and exposed to hygrothermal conditions are studied. The elastic coefficients, thermal coefficient and moisture expansion coefficient of the plate are assumed to be exponentially graded in the thickness direction. The trigonometric shear deformation theory solution is presented. In this solution, the initial terms of a power series through the plate thickness are used for the displacements in addition to other trigonometric terms. The effect due to transverse shear deformations is included. A number of examples will be solved to illustrate the numerical results concerning bending response of homogeneous and exponentially graded rectangular plates subjected to hygrothermomechanical effects. The influences of temperature, moisture concentration, transverse shear deformation, plate aspect ratio, and the exponentially graded parameter on the bending response are investigated.
