Deformation properties of multi-wall gold nanowires under compressive loading are studied. Nanowires are simulated using a realistic many-body potential. Simulations start from cylindrical fcc (111) structures at T = 0 K. After annealing cycles axial compression is applied on multi-shell nanowires for a number of radii and lengths at T = 300 K. Several types of deformation are found, such as la...
