AbstractA two-dimensional gain-based lattice approach is developed here driven by the needs for modelling strategy of rock salt (halite). In this scheme considering crystalline micro-structure halite is discretized into polygonal grains by smooth joint logic in which mass nodes with micro-rotation are connected by springs. The contacts between grains are in a point-to-point manner which can avoid complex contact definition (point-to-edge or edge to edge etc.) in classical numerical simulations. Breakage and creation of interactions in dynamic spring network is applied to implement the dislocation and diffusion within grains in addition to crystal plasticity.
