It is shown that fractal analysis, as an additional tool of technical diagnostics and non-destructive testing, allows determination of the most important features of the state and behaviour of metal structure elements during their operation and failure. Examples of application of fractal dimension of the fractures are presented to assess the critical dimension of brittle cracks and to determine its effect on impact toughness, yield limit, ultimate strength, and destructive pressure at hydraulic testing, and to detect the interrelation of fractal dimension with fatigue life after low-cycle fatigue fracture of metal of pipeline welded joints. It is found that the nature of fractal dimensions of the fractures and diagrams of time dependence of the applied load at impact loading is due to the direction of cutting and temperature of testing the samples. It is shown that the main component of {001} <110> texture of low-alloyed steel promotes an increase of fractal dimension of the fractures and development of brittle fracture at impact testing.
