Abstract:In this work, bending properties of five-layer sandwich panels with corrugated three-layer core are investigated both numerically and experimentally. Sheet metal forming is employed to construct the corrugated core and three-point bending tests are performed to experimentally evaluate the bending behavior of the panels. Besides, reliable finite element model is developed and validated by the experimental results. The results show that the phase difference of the external core has no considerable effect on the … Show more
