Abstract

Interlaminar THERMAL STRESSES and boundary layer effect in thin laminated composite cylinders which are subjected to temperature change are studied. To this aim a laminated cross-ply composite cylinder with finite length which is subjected to thermal loading is modeled. The DISPLACEMENT BASED LAYER-WISE THEORY (LWT) is used for modeling the response of the composite cylinder in the thermal loading conditions. Using an appropriate displacement field and employing the LWT, the governing equations of the cylinder and the appropriate boundary conditions in the edges of the cylinder are derived with the principle of minimum total potential energy. An analytical solution is introduced for the governing equations and the solution is obtained for various boundary conditions. The numerical results are validated by comparison of the results of LWT with the predictions of the finite element method (FEM) and good agreements are seen. It is shown that the presented LWT solution is an efficient and accurate method for analysis of the edge effect and interlaminar stresses in composite cylinders. The interlaminar THERMAL STRESSES and in-plane stresses in the Glass/Epoxy composite cylinder which are subjected to thermal loading are investigated for various boundary (edge) conditions. Cylinders with symmetric and asymmetric layer staking and free, simple and clamped boundary conditions are studied in the numerical results.
