摘要：The sandwich plate with folded core is a new type of sandwich structure.It has good design ability and has gained interest in the aerospace industry as a promising sandwich core structure.In this paper,energy absorption characters of M-type folded core are studied.Finite element models are set up for folded cores with different geometric parameters.The calculation result of the finite element model agrees well with the experiment data.And the energy absorption coefficient of folded core is 2.6 times as much as the coefficient of honeycomb core with the same height and density.Besides,influences of each geometric parameter on energy absorption characters are analyzed.And some useful results have been obtained.These results can be helpful when designing folded core as anti-crash structure.
