Influence of Adhesive Reinforcement on the Mode I Fracture Toughness of a Bonded Joint
Abstract
The influence of adhesive reinforcement on the fracture toughness is investigated with a computer model based on a variational theorem that has been shown to accurately predict stress fields and energy release rates for cracked laminates. An axisymmetric damage plane strain model was developed and used to determine the Mode I energy release rate for midplane cracking in aluminum bonded specimens with varying amounts adhesive reinforcement. The calculated energy release rates are compared to closed form analyses in a systematic test program.
