This thesis work involves an initial study on Stress Concentration caused by holes out of center in thin plates of finite width made of Unidirectional and Crossply Fiberglass Composites. The results are reported under the form of the Stress Concentration factor K. as a function of two nondimensional tg parameters, one representing the eccentricity of the holes, and the other representing the influence of the size of the holes. The graphs plotted for K permit their use for thin plates of different dimensions.
