Abstract
The quasi-static cracking technique has been extended to include fracture toughness measurement of materials with residual stresses. Theoretical analyses are presented which show that the effective fracture toughness and residual strain energy could be readily evaluated using this approach. Experiments on adhesive joints with prior-introduced residual stresses gave results in good agreement with theory. A simple graphical method to measure the genuine fracture toughness of materials with residual stresses is proposed and verified. Additionally, conditions for the fracture of slender beams glued to rigid substrates due to swelling were given and discussed.
