- Fracture Mechanics Evaluation of Adhesive Joint by Digital Image Correlation
抄録
<p>In a recent automotive industry, the weight reduction of vehicle body is required for intense fuel efficiency regulation. Multi-material structures such as steel with aluminum or CFRP has been adapted nowadays. Adhesive bondings are attracted for joining different materials, but the reliability of adhesive joints under various loading conditions are important issues. Therefore, fracture mechanics evaluations of adhesive joints in mixed mode loading are required, but it has not been established yet. In this study, a method for obtaining J-integral values from path integrals using the Digital Image Correlation(DIC) as the fracture mechanics evaluation method of the adhesive bonding material is studied. At first, we adapted the developed method to aluminum alloy A5052 and confirmed that J-integral values from DIC is agree with that of FEM analyses in mixed mode tensile tests. Then the developed method was applied to adhesive joints and comparison between experiment and numerical results were discussed.</p>
