Bending resistance of single honeycomb paper-core under axial dynamic load has been analyzed to meet the need of honeycomb paperboard produce. First, the models were built after buckling theory analysis. Dynamic characteristics of compressive process were analyzed in the FEA software. It was indicated that: When the height of model was lower than a certain value, the process was divided into four parts: linear elastic phase, elastic-plasticity phase, plasticity collapse phase and densification phase. However, when the height of model was above than the certain value, the model was easy to bend in the intermediate region. Some results such as force and shearing stress had been gotten. At last, the compressive process was verified by experiment, which was bigger value due to air and glue water existed in honeycomb core.
