Abstract
The fatigue crack kinetics in the residual stress field is investigated in the specimens of TC4 titanium alloy after their laser shock peening (LSP). Following this treatment, the fatigue tests are carried out. The fatigue life of the specimens after LSP is found to increase. The maximum applied force in the fatigue cycle, which compensates for the residual stress effect, is determined by a numerical simulation. This determines the range of applied forces within which the compressive residual stress field generated by LSP remains effective.
期刊介绍：
Russian Physics Journal covers the broad spectrum of specialized research in applied physics, with emphasis on work with practical applications in solid-state physics, optics, and magnetism. Particularly interesting results are reported in connection with: electroluminescence and crystal phospors; semiconductors; phase transformations in solids; superconductivity; properties of thin films; and magnetomechanical phenomena.
