Abstract : In this paper the combination of the theoretical, numerical and experimental study of stresses, deflection and free vibration of (stainless steel mesh, random E-fiberglass, and Epoxy resin) anti-symmetrically laminated composite plates subjected to a uniformly distributed load for simply supported boundary condition are investigated. The theoretical analysis which based on (Kirchhoff’s Hypothesis) is conducted. The numerical analysis which based on Finite Element Method (FEM) by using ANSYS program is conducted and the experimental setup and procedure of the modal testing method and fabrication procedure of the laminated composite plates is described. A computer program based on Finite Element Method (FEM) ANSYS has been developed to perform all necessary computations. The results are compared with the analytical and experimental results. The stresses, and deflection of 3, 6, 9 and 12 layered simply supported laminated composite plates has been determined analytical and compared with FEM, and natural frequencies has been determined experimentally and compared with both methods analytical and FEM. The mode shape of the plates has been determined using ANSYS package. Once the analytical, FEM and experimental had been validated, the effects of the fiber orientation and number of layers to the stresses, displacement and natural frequencies values was conducted for different cases of anti-symmetric 3, 6, 9, and 12 ply layup. Keywords - Composite laminated plates, Classical Laminated Plate Theory (CLPT), Finite Element Method.
