Paper Title:
The Dependence of the Energy-Absorption Capacity of Metal Hollow Sphere Materials on their Relative Density
  Abstract

Experimental, numerical and theoretical analyses are carried out to obtain the relationship between the stress and relative density of metal hollow sphere (MHS) materials during their large plastic deformation in order to estimate the energy absorbing capacity of these materials under uniaxial compression. Based on a numerical parametric analysis empirical functions of the relative material density are proposed for the elastic modulus, yield strength and ‘plateau’ stress for FCC packing arrangement. Analytical stress-strain dependences are suggested for the yield strength and material strain hardening properties as functions of the relative density of MHS materials under uniaxial compression.
