Parallel Quasicontinuum Branch-Following and Bifurcation

Static multiscale quasicontinuum simulations aim to obtain a stable equilibrium configuration (local energy minimum) of a body composed of discrete atomistic and finite element regions subjected to external loads such as forces and/or displacements. This project involves the novel application of branch-following and bifurcation (BFB) methods to multiscale problems, by studying a quasicontinuum simulation of nano-indentation into a Ni thin film.
