Research on Compressive Performance of Honeycomb Paperboard
Abstract:
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.
