本文研究了以金属泡沫填充折叠板为芯材的完全固支波纹夹层梁在低速冲击下的响应。考虑泡沫金属和折板的强度效应，得到了泡沫金属波纹夹层梁截面的屈服准则。基于屈服准则，分别建立了波纹夹层梁大挠度的动力和准静态分析模型，与有限元结果吻合较好。此外，它表明，面板和折叠板的应变硬化没有显着影响低速冲击响应。
The paper focuses on fully clamped corrugated sandwich beams with metal foam-filled folded plate core to investigate its response subjected to low-velocity impact. The yield criteria for the metal foam-filled corrugated sandwich beam cross-section are obtained by considering the strength effects of metal foam and folded plate. Based on the yield criteria, dynamic and quasi-static models are developed to analytically predict the large deflections of corrugated sandwich beams, respectively, which agree well with finite element results. Furthermore, it is shown that the strain hardening of face sheets and folded plate do not significantly influence the low-velocity impact response.
