13th International Conference on Fracture June 16–21, 2013, Beijing, China -8- Figure 13. Component εp zz of plastic strain tensor (cross section by the Oy plane) Figure 14. Component pxz of the deformation tensor caused by defects Figure 15. Component pzz of the deformation tensor caused by defects Also, there was carried out an experiment on the compression of titanium specimen of the same shape and the same sizes. The titanium with small grain size (about 0.3 mkm) is more brittle material then vanadium. The compression of this material is accompanied by crack initiation. Figure 16 presents a temperature distribution of the cracked specimen surface.
