Kalın ve katmanlı kompozit plakaların temel doğal frekansının mekanik özelliklerin küçük değişimlerine duyarlılığı.

The design of composite plates according to the desired properties is usually performed by trial and error. This prolongs the final design process. Therefore, it is very important to determine the effective design parameters on the desired design objective function in design processes. In this regard, sensitivity analysis is one of the frequently used methods. In this study, the sensitivity analysis of the fundamental (first) natural frequency of thick layered composite plates with different thicknesses was performed. The elasticity modulus perpendicular to the fibre and among the fibre and the shear modules in the three directions are selected as design parameters. Then, natural frequencies corresponding to the combination of design parameters were calculated with finite element based Monte Carlo simulation. Next, a mathematical model was constructed to perform. As a result, the sensitivity of the fundamental natural frequency was obtained depending on the thickness. [ABSTRACT FROM AUTHOR]
