| چکیده | ||
| In this paper a special sandwich panel with a sinusoidal core under distributed load on upper and lower plates has been studied. By drawing free body diagrams, and using energy method and Castagiliano theory the forces and moments involved in the core has been determined. Then, the stresses, normal and horizontal displacements due to above forces and moments are calculated. In order to ensure the accuracy of the analysis, the results obtained are verified by using ANSYS software. Finally, by use of displacement as a constraint for sandwich panel, optimization is carried out for this problem by genetic algorithm and MOEA toolbox in MATLAB environment. The results obtained from optimization and other analysis show a very good agreement. | ||
