Stress Intensity Factors for Cracks Emanating from a Circular Hole in Laminated Composite Infinite Plate Under Different Loading Conditions
General solutions for determining the stress intensity factors, for cracks emanating from circular hole in laminated composite infinite plate subjected to arbitrary loading, with layers of arbitrary fiber orientations and stacking sequence, are obtained using Muskhelishvilipsilas complex variable method. The stress functions are obtained by evaluating Schwarzpsilas integral for the given boundary conditions. The generalized formulation thus obtained is coded and numerical results are obtained using MATLAB 6.5. The effect of crack orientation, loading pattern and fiber orientation is studied for orthotropic and isotropic plates. For some of the cases half crack plane stress model are prepared in ANSYS and results are compared with present method.
