Shear-induced homogeneous deformation twinning in FCC aluminum and copper via automistic simulation
(Massachusetts Institute of Technology, 2003)
The {111}<112̄> shear stress-displacement behavior for face-centered cubic (fcc) metals, aluminum and copper, is calculated using empirical potentials proposed by Mishin and by Ercolessi, based on the embedded atom method ...
Stress-mediated reaction pathways for dislocation nucleation in copper
(Massachusetts Institute of Technology, 2007)
The ductile behavior of metals requires dislocation nucleation, from either homogeneous or heterogeneous sources, in order to produce the large number of dislocations necessary for extensive plastic deformation. As with ...
