• General criterions for determination of the local stress state at the crack tip of the materials under different types of loading conditions such as: i) static, ii) impact, iii) high-speed impulse, iv) impact-cyclic, v) cyclic are proposed. They are the ratio of the maximum depth plastic zone to the specimen thickness (<I>h</I><SUB>max</SUB>/<I>t</I>) and the ratio of the diffraction line width obtained from the fracture surface to the diffraction line width obtained from the unstrained metal ( β/β<SUB>0</SUB>). The plane strain deformation condition under static and cyclic loading conditions may be defined more precisely using by above criterions. X-ray techniques for determination: i) material fracture toughness of the failed construction, ii) critical fatigue crack length <I>l</I><SUB>s</SUB> and <I>l</I><SUB>f</SUB>, iii) stress of the loading cycle, iv) load ratio <I>R</I>, v) track growth speed are presented. If the fracture surface was completely damaged by corrosion or mechanical affect, X-ray techniques may be used for identification of the type of the fracture surface.
