An experiment in strain hardening. The bending of a piece of metal, such as a paperclip, results in strain hardening where the deformation is largest. Subsequent backward bending leads to deformation in places where little strain has accumulated in the forward process. This seemingly simple process still cannot be mode led accurately. Dislocation simulations by Madec et al. now provide new insights (2).
