Two ideal deformation scenarios, homogenous and progressive collapse, were
used to characterize the energy absorbing capacity of metallic foams under quasi-static
axial compression in regime 4 (Lopatnikov, et al. 2007). These collapse scenarios were
compared with elastic-plastic-rigid (EPR) and elastic -perfectly plastic-rigid (EPPR)
foam models (Figure 2.28). The developed theoretical models based on the deformation
scenarios predicted the same energy absorption values with EPRS foam.
