Dynamic creation and evolution of gradient-nano-grained structures in single-crystal metallic microcubes

In an article published today in Science, we have demonstrated the creation of an extreme gradient-nano-grained (GNG) structure in single-crystal microcubes through high-velocity impact. We use the defect-free single-crystal silver microcubes, synthesized using a seed-growth process, as the model system, and fire them at supersonic velocities onto a rigid target to create the GNG structure.

Two-Dimensional Analysis of Equal Channel Angular Extrusion using ABAQUS

I am trying to model ECAE in ABAQUS, but I have a problem regarding the boundary conditions.Does anybody have experience with this problem?
