Research on Compressive Performance of Honeycomb Paperboard
Compressive performance of honeycomb paperboard was studied by way of FEM and verified by experiment. First, the collapsing process was divided into four parts: linear elastic phase, elastic-plasticity phase, plasticity collapse phase and densification phase. Second, the models were built on the FEM software and analyzed their nonlinear collapse process. It could be known that: the damage started in the intermediate region of honeycomb core; the collapse process met the theory analysis; the models with different side length of paper-core had a bearing up on compressive strength. At last, the results were verified by experiment, which was bigger value due to air and glue water existed in honeycomb core.
