논문 초록 (Abstract)

This study aims to predict the mode I and II fracture behaviors of a composite adhesion interface by considering the effects of temperature. The fracture behaviors in environments at –30 °C, 24 °C, and 60 °C degrees were predicted. The parameters required for ABAQUS CZM were determined based on basic material properties and interlaminar fracture toughness tests with respect to temperature. The obtained parameter values were applied to conduct progressive failure analyses. The DCB and ENF models, which exhibit mode I and II fracture behaviors, respectively, were used for these progressive failure analyses. Furthermore, the analysis and test results were compared, indicating a maximum difference of 14.25 %.
