摘要: Abstract In this study, comprehensive investigations of an innovative composited cellular structure—Honeycomb cells filled with circular aluminum tubes (HFCT) are conducted by means numerical simulation and theoretical analyses. A conventional honeycomb was modeled to calibrate the model a good agreement between experimental results achieved. With calibrated model, extensive comparisons mechanical performances considering deformation modes, nominal stress energy absorption property were carried out in terms HFCT, honeycomb, multi-tubes. The interaction effects internal filler outside container HFTC discussed through comparison representative volume elements (RVE) three structures. addition, obvious matching cell thickness observed HFCT. Afterward, based on minimum principle which basic fold element HFCT constructed determine key compression characteristics (half-wave length plateau stress). Agreement them found geometrical description post-deformation mode.
