Vibration analysis of plates has been an active research subject of engineering field. The analytical solutions have been found for plates with specified forms of mass and stiffness modifications, but for the plates with uncertain mass and stiffness modifications have not been addressed confidently. The concept of uncertainty plays an important role in the design of practical mechanical system. So it becomes important to study its effects on mechanical system for different frequency domain i.e. low, medium and high frequency. Here in this paper structural element square plate with all edge fixed boundary condition is selected on which mass, stiffness and combination of it, uncertainty is taking in account. By using Finite Element Method technique finding out, how plate is dynamically behaves in vibration. During modal analysis natural frequency and mode shapes are find and compared the response of bare plate and the plate with mass, stiffness ,mass-stiffness combination uncertainty.
