Abstract

Surface layer and all interfaces in a solid under loading are considered as an autonomous functional subsystem where the primary plastic shears are initiated and developed. The grain boundaries nonlinear wave flows are depended on a crystal lattice curvature. Computer simulations of grain boundaries rotational wave flows for various lattices curvature were performed using modified excitable cellular automata technique. This method is offered for taking into account the grain boundary flows for the sake of computer simulation of polycrystal's behavior under deformation and fracture as well as during processes to take place in additive manufacturing technology.
