Materials with isotropic behavior are generally used for engineering purposes because they exhibit uniform property but in current scenario materials are used for multipurposes so they required to show variation in property as per requirement. Composite materials shows aelotropic behaviour and their property can be controlled and a single material can show different property in different direction within a controlled manner. As the composite plates are hybridized and their is variation in layup sequence, the dynamic behaviour of plates vary continuously. Variation in the aspect ratio of composite hybridized plate may also results in variation in property. These variations influence the natural frequency , displacement , stiffness and mode shapes of plate which can be investigated by detailed parametric analysis with the help of Ansys Workbench 14.O software .From the observation it can be observed that dynamic behavior of composite plate of Steel +Kevlar is better than other lay up sequences and as thickness increases dynamic resistance also increases.
