In order to improve industrial machining processes, a good understanding of plasticity of bulk metals is required. In metals, plasticity is strongly dependent on the microstructure of the material. At micron scales, the orientation and size of single crystal grains becomes important. At sub-micron scales, closely packed packed crystalline planes and crystalline defects such as dislocations become increasingly important. Here we present molecular dynamics simulations of strained crystalline structures. Particular attention is given to micropillar compression testing, an experimental technique in which micron scale single crystal pillars are compressed.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
