Nanoindentation experiments are an excellent probe of micromechanical properties, but their interpretation is complicated by their multiscale nature. We report simulations of silicon nanoindentation, based on an extended version of the local quasicontinuum model, capable of handling complex Bravais crystals. Our simulations reproduce the experimental load vs displacement curves and provide microscopic information such as the distribution of transformed metallic phases of silicon underneath the indenter. This information is linked to the macroscopic electrical resistance, giving a satisfactory explanation of experimental results.
