structure of tubes made from one kind of the material showed the initial porosity has a direct effect on the formation of 3D fragments. According to the scenario, the initial defect (porous) structure generates the conditions for reproducing the multi-site fracture of ceramics under high rate loading. The greater is the tensile stress, the higher number of pores will become a centers of damage initiation.
