High intensity heating of aircraft structures can challenge the structural integrity of critical aircraft components, especially when they may contain flaws. The evaluation of flawed components requires the application of fracture mechanics wherein crack tip stress intensity factors are used to provide a quantitative means of assessing structural integrity. The primary objectives of this project were to develop an analysis method for computing stress intensity factors for severe thermal loadings of interest to the Air Force and to demonstrate the applicability of the method to small microcomputers.
