The main objectives of the program are to study crack tip stresses and crack tip deformation, and to use the findings of these studies to investigate the fractures of ductile and tough materials. Crack tip displacement and strain fields were measured with the moire method, and crack tip stress, displacement, and strain fields were calculated with the finite elements method. The measured displacement and strain fields agree well with the finite element calculations. The results were used to develop the direct correspondence method of evaluating fracture toughness of ductile tough materials and were also to analyze deformation mode of fatigue crack growth.
