(This message was sent to iMechanica by Ken Chong, of the National Science Foundation). This letter is to call your attention to an opportunity to broaden participation particularly of underrepresented students in Ph.D. programs in engineering through supplements to current research grants funded by the divisions in the Directorate for Engineering (ENG) at the National Science Foundation.
The main idea is the following: a most natural mathematical setup for considering the motion of the void-solid interface of an expanding void is that of the traveling wave. Thus, a theory for macroscopic damage evolution may be suspected as being a homogenized version of basic theory that has such wave phenomena as an essential ingredient. This paper is a first step in probing such questions.

Mechanism-based discrete dislocation
plasticity is used to investigate the effect of size on micron scale
crystal plasticity under conditions of macroscopically homogeneous
deformation. Long-range interactions among dislocations are naturally
incorporated through elasticity. Constitutive rules are used which
account for key short-range dislocation interactions. These include
