Abstract :
A study on analysis of stress intensity and stiffener debonding damages is presented for stiffener bonded composite laminate with multiple site damages using complex potential solutions. It revealed that the stiffener debondings made a significant influence on significant increase of stress intensity near crack tips and/or slits, which can be led to a catastrophic failure of stiffened composite plates.
