摘要: Abstract A comparative study of energy absorption characteristics between foam-filled square columns and multi-cell was conducted by using nonlinear finite element codes LS-DYNA. The the foam were made same material aluminum thickness all sidewalls kept 1.5 mm. Numerical results compared well with theoretical predictions showed that efficiency about 50–100% higher than columns. It means more attractive reason for this analyzed a comparison collapse modes. Furthermore, type pre-crushed trigger introduced modeled This found to be effective eliminate initial peak force improve column as an absorber.
