The current research dealt with the system of cantilever beam, which has holes of various shapes on its surface, under the influence of direct external load. The design of the system control of four three-dimensional models consisting of steel and various composite materials was modeled and simulating by the use of ANSYS program, using finite element technology. The results of modeling in the ANSYS program using the finite element technique show that the values of the deflection in the models consisting of different composite materials increased by various percentages when compared to the model consisting of steel, with the model consisting of fiber class having the highest value. The displacements in these models also increase at rates almost similar to the percentage of deflections. According to the results, the various stresses that resulted from the steel model in the composite models were reduced by around a third, except for shear stress values, they increased in the composite material models, by more than a third compared to the shear stress in the steel model. The results of strains indicate an increase in the models composed of composite materials in different proportions, with the highest values (92.18%) in the model consisting of fiberglass. The results of the strains and stresses obtained at the seven points and distributed in order at the holes on the surface of the four models located in the path (A - A) most of the increments were at the third point, While the highest value of displacements was at the fifth and eighth points.
