Abstract The bearing capacity of structured materials and the character of their fracture depend on the response of structure elements to the loading conditions. An example of analysis of elasto-brittle fracture of materials containing pores or microcracks is used to illustrate the differences in mechanisms of their fracture in the situations of external compression.

We consider the mechanism of influence of structures of these types on the material fracture initiation and the dilatancy due to variations in the stress state and on the character of development of main fractures formed by unifying the cracks growing near active elements of the structure.
Keywords crack, structure, limit state, dilatancy
