Coarse-grained atomistic modeling

Several significant advancements in the concurrent atomistic-continuum (CAC) method have been made: (i) new types of finite elements are developed which yields a more accurate stacking fault energies and core structure in coarse-grained atomistic descriptions of dislocations [2], (ii) zero temperature, quasistatic CAC approaches are formulated to enable the constrained multiscale optimization for a sequence of non-equilibrium dislocation configurations in metals [2], (iii) mesh refinement schemes for both dynamic fracture and curved dislocation migration are implemented [5], (iv) the CAC method is extended to body-centered cubic systems [13], and (v) the code efficiency is improved using parallelized object-oriented programming in a parallel code [11] and a CAC simulation environment named PyCAC [12].

CAC simulations are performed to study multiple plasticity problems in a variety of crystals, including compression of nano/submicro-pillars in W [13] and Au [14], H diffusion in Fe [18], dynamic fractrue in Cu [5], fast moving dislocations in Cu [3], screw dislocation cross-slip in Ni [8], edge dislocation bowing out from a row of collinear obstacles in Al [6], dislocation multiplication from Frank-Read sources in Cu, Ni, and Al [7], dislocation-void interactions in Ni [1], dislocation-obstacle interactions in Al [15], dislocation-stacking fault interactions in Ni, Al, and Ag [10], misfit dislocation evolution in (111) Si/Ge interface [16], {111} Ni/Cu interface, and {111} Cu/Ag interface [17], as well as sequential slip transfer of curved dislocations across a Σ3{111} coherent twin boundary in Cu, Al [4], and Ni [9], a Σ11{113} symmetric tilt grain boundary in Ni [9], and a (111) semicoherent interface in Si/Ge bilayers [16].

In the context of a single type of lattic defects, atomistic simulations are used to study dynamics of a dislocation in Cu [19], dislocation walls in Cu thin films [16], as well as Peierls stress of a dislocation in Mo [24], Nb [23,24], Ta [24], W [24], and W-based random binary alloys [40].

In the context of multi-defect interactions, atomistic simulations are used to study interactions between a dislocation and a void [19] or a helium bubble [33] in Cu, dislocation nucleation from grain boundaries in V [13], vacancy-aided grain boundary migration in Cu [18], and solute-enhanced twin boundary migration in CuAg alloy [43].
