Strain hardening during constrained deformation of metal foams–Effect of shear displacement
Scripta Materialia, 2009•Elsevier
The crush bands that form during plastic deformation of closed-cell metal foams are often
inclined at 11–20° to the loading axis, allowing for shear displacement of one part of the
foam with respect to the other. Such displacement is prevented by the presence of a lateral
constraint. This was analysed in this study, which shows that resistance against shear by the
constraint leads to the strain-hardening effect in the foam that has been reported in a recent
experimental study.
