Abstract |
|
In this paper, solutions for a transversely loaded simply supported case with several different plate configurations based on extended higher-order sandwich panel theory (EHSAPT) are outlined and numerical results are presented. The results are also compared to established elasticity solutions and validation of EHSAPT for plates of arbitrary aspect ratios is made. The results are also compared to existing classical and first-order shear models for completeness. The results show excellent agreement both for displacements and stresses through the core. Analytical formulations and solutions to the natural frequency analysis of simply supported composite sandwich plates are also presented. The effects of variation of geometrical parameters of the structure on the natural frequency are also studied. |
