Composite plates are formed by lamination of matrix phase and reinforcing phase . Composite plates are most widely used to retain soil therefore they can be used in under-ground constructions. Composite plates shows aelotropic behaviour and a single plate can show different property in different direction within a controlled manner.Here steel is used as matrix phase and Kevlar is used as reinforcing phase. As the composite plates are used to retain soil due to presence of water, these plates are subjected to seepage forces. In order to reduce the effect of seepage force cut-outs are provided. Shape of cut-outs, position of cut-outs effect the dynamic behaviour of plates. Cut-outs are provided concentrically or eccentrically (one way and two way) may also effect the dynamic behavior of plates. These variations influence the natural frequency , displacement , stiffness and mode shapes of plate which can be investigated in detailed with the help of ANSYS Workbench 14.O software which work on finite element method. From the observation it can be observed that dynamic behavior of composite plate with circular cut-out is better than that of composite plate with rectangular cut-out . As the cut-outs are provided more eccentrically, the dynamic behavior of plates becomes more better with respect to concentrically placed cut-outs. Plates provided with two way eccentric cut-outs shows better results compare to plates provided with one way eccentric cut-outs.
