Many problems in fracture mechanics are not readily amenable to analytical treatment. Stress distributions and stress intensity factors cannot always be calculated easily for a given structural geometry and loading condition. However, finite element methods offer an accurate, versatile, and conceptually simple means by which a given structure can be analyzed. They allow a general application of classical crack propagation analysis whereby the necessary estimates of the stress intensity factor may be calculated. The report presents the development of a general finite element method commonly used in structural mechanics and several finite element approaches employed specifically in fracture mechanics for computing stress and displacement functions, and stress intensity factors for a cracked structure.
