Three Dimensional Coupling between Elastic and Thermal Fields in the Static Analysis of Multilayered Composite Shells

This new work aims to develop a full coupled thermomechanical method including both the temperature profile and displacements as primary unknowns of model. generic 3D exact shell model permits thermal stress investigation laminated isotropic, composite sandwich structures. Cylindrical spherical panels, cylinders plates are analyzed in orthogonal mixed curved reference coordinates. The equilibrium relations Fourier heat conduction equation for shells they trivially can be simplified those cylindrical panels. exponential matrix methodology is used find solutions based on differential with respect thickness coordinate. analytical solution theories simply supported edges harmonic displacement components sovra-temperature. sovra-temperature magnitudes directly applied at outer faces through static state hypotheses. As consequence, description assumed an unknown variable it calculated same way three displacements. final system set homogeneous second order reduced first relation by redoubling number unknowns. Therefore, calculate solution. field effects evaluated terms components. After appropriate preliminary validation, benchmarks discussed several ratios, geometrical data, lamination sequences, materials values imposed faces. Results make evident accordance between uncoupled thermo-mechanical this without need separately solve relation. Both connected layer related embedded included conducted analysis.
