Abstract: Considering the importance in the applications of the composites in many fields (aerospace industry, automotive industry etc.), it is necessary to build the composite which withstand high strength and high temperature. For achieving this, knowledge of failure criteria is most important in terms of machining of the composites which is drilling in this study) (6). Tsai-Wu failure criterion is the only failure criteria suitable for isotropic composites (8). In this work the Tsai-Wu failure criteria is used to find the failure index by using ANSYS v12.0 for different point angle of drill bits(1100 and 1180 ) with reference to the experimental data and literature for the drilling of CFRP composites. The FE constitutive model provides the solution for the damage in the FRP specimen by taking various drill-tool geometries as per experimental studies.
