Abstract

The applications of composite materials in civil engineering cannot be under-emphasized due to their high strength to weight ratio. The laminates are exposed to moisture variations and are often the predominant reason for failure of composite structures. Moisture distributed throughout the volume of the structure may induce residual stresses and extensional strains. Cutouts are often made to lighten the structure for ventilation and accessibility for inspection to other parts of the structure. When the laminates with cutouts are subjected to changes in moisture content the deformations and stress concentrations are observed which may result in the laminate to detach from the structure. The present study is focused on the bending characteristics of plates and shells laminates having different lamina and different boundary conditions subjected to change in moisture content. The formulation is done using six node second order linear strain triangular elements. A standard SSSS plate problem is analysed and the results are validated.
