Essay

Static fracture toughness heat-resistance steels.The purpose-development techniques of influence prestress cyclic loading on a basis local facture criterion. Is submitted techniques of prediction of influence prestress cyclic of elasto-plastic deformation smooth specimen on static fracture toughness, which is founded on the analysis of mechanism cyclic deformation in view of dependence ?сl from parameter of a prestress cyclic loading. Creation a forecasting technique in view of influence prestress cyclic loading (amplitude and amount of cycles) heat-resistance steels at a stage propagation of fatigue crack growth on static fracture toughness. The area of application-prediction of the construction life time, the further scientific researches.
