Resumo·duip a cost. weight, and et&.:rgy efficient bumper .....,. absorber, it is important to consider optimizing of eorins employed in the design of the system. i1:11..,.11'. a aumber of foam coring patterns arc studied .,.....piriul and aalytical methods. The size and Of •DRtPOtllld core desips are studied in detail with ._llitleaiveo to several·differcnt densities of polyp!Op)'leae (EPP) foam. Using the fmite ••ltllad of lb'Uctural analysis, it is possible to have look at the stress distribution dwins deformation ,cruotures. An optimization study using the finite mathod is conducted using the energy absorption efT~eiency parameter. Several coring patterns are recommended for bumper foam core design oa bip energy absorption efficiency and low tear
