“…8 Many studies have been taken on trapezoidal and triangular corrugated core sandwich structures commencing from 2009 to 2021 to analyze the behavior of the corrugated structures under compressive load at different rates. [9][10][11][12][13][14][15][16] Also, due to their low-cost raw materials of polymeric foams, they have been used in the core fabrication, hence they play a significant role in the cost-effective production of sandwich panels. 17 Kılıçaslan et al investigated the multi-layer trapezoidal aluminum cores under local impact using spherical, conical, and flat-head impact applier.…”

The present paper tries to introduce the effect of foam-filled on a type of trapezoidal corrugated core and their structures derived from the related previous studies. The main purpose of this work is to present a novel geometry of trapezoidal cores, and their configurations are inspired by the earlier works. These absorbers have been proposed to raise the specific energy absorption (SEA) while declining the initial peak crushing force. Therefore, five corrugated core sandwich panels have been tested under quasi-static axial compressive load experimentally and then simulated by ABAQUS software. The accuracy of the numerical simulations is validated by comparing the numerical results with the corresponding experimental data. Besides, some other simulations have been carried out to investigate the effect of foam density, core type, and thickness in more detail. The comparison results show that the SEA rate of bi-core sandwich panels which has not been filled by foam is better than the single trapezoidal core sandwich panels, and this rate is roughly around 70%. The best performance is relevant to the pure foam core without any trapezoidal core structure and the next item is the single foam-filled corrugated core and the lowest performance among them is related to the bi-core corrugated core foam-filled.
