- This paper demonstrated the crucial role of dislocation source density in the smaller is stronger size effect. It required the development of a new coupled 2D DD/FEM matlab code which is now widely used by researchers at Imperial and Oxford. The approach demonstrated that micromechanical tests on end loaded cantilevers in special orientations could be accurately simulated in 2D at the discrete dislocation level, providing a new tool the analysis of small scale tests.
