THE CRITICAL DEPTH OF A NON-PROPAGATING FATIGUE CRACK AND THE REGULIARITIES OF ITS FORMATION

The dependence of the stresses intencity coefficient on the cylindrical parts crack depth has been examined. The connection between the critical depth of a non-propagating fatigue crack and the stresses intencity coefficient has been stated

THE CALCULATION DEFINITION OF STRESSES INTENCITY COEFFICIENT IN THREADED PARTS WITH RESIDUAL STRESSES

The dependence of the stresses intensity coefficient on a crack size in non-hardened and hardened bolts M6 made of a titanium alloy ВТ 16 is studied

THE ENDURANCE LIMIT OF SURFACE HARDENED CYLINDRICAL PARTS MADE OF CONSTRUCTION STEELS PREDICTION

The results of the hardened parts made of construction steels endurance limit prediction after pneuma- and hydro shot-blastig are presented in the study. The results of the calculation have been compared with the results of the fatigue tests

THE INFLUENCE OF THE NITRIDIED LAYER DEPTH ON THE ENDURANCE LIMIT OF PLATE SPECIMENS MADE OF STEEL 30ХГСА

The influence of the nitridied layer depth on the endurance limit of plate specimens made of steel 30ХГСА has been studied. It’s been stated that the optimal depth of the nitridied layer for specimens of the 3 mm thickness is 0,10-0,12 mm
