Abstract

The paper is devoted to development of the structural model of metal-ceramic composites within the framework of numerical discrete element method. The model takes into account main features of multiscale internal structure of composites such as content of reinforcing ceramic particles whose sizes are distributed within several structural scales, width and mechanical properties of transition zones at interphase boundaries and so on. Capabilities of the developed discrete element-based model are demonstrated by the example of numerical study of features of fracture of NiCr-based metal-ceramic alloy with TiC inclusions.
