This final technical report presents a summary of a three years project in which the mathematical basis of failure criteria for metals and composite materials was investigated. The investigation covered criteria associated with crack formation and structural instability. The main results are a General procedures for the determination of mathematical functions that model the conditions for crack formation at critical points were developed and implemented into a generally available computer code. b Mathematical models for buckling failure were formulated, implemented and their properties clarified.
