Methods for experimental and computational assessment of the dissipation indicators of the endurance limit and cyclic durability of power lugs of machines and mechanisms are presented. Based on a generalization of the results of fatigue tests, the dependences of the standard deviation of the logarithm of the number of cycles before failure of lugs made of high-strength steels on the maximum amplitudes of cyclic stresses were constructed. Formulas are obtained for calculating the coefficient of variation of the theoretical stress concentration coefficient of the lugs from production deviations of their dimensions in plan and from the dispersion of the gap between the bolt and the hole. Based on these formulas, the values of the coefficient of variation of the theoretical stress concentration coefficient for typical lugs are obtained and given.

The features of the fatigue strength of the lugs in different zones of the cycle asymmetry coefficient are considered. It is shown that the most severe conditions of variable loading of the lugs correspond to a cycle asymmetry coefficient from 0.1 to 0.2. Formulas have been obtained to clarify the statistical assessment of the durability of symmetrical lug samples when, during their fatigue testing, destruction occurs on only one side. Recommendations are given for the selection of accelerated test modes with forced loading and for comparative tests at the same stress amplitude level.

The article considers the issues of energy distribution and use management by means of modeling changes in the electrophysical characteristics of semico nductor structures under the influence of static radiation. The change in the main electrical parameters of transistor structures is given, such as, change in the concentration of the main charge carriers, change in specific resistance, change in the mobility of charge carriers, change in threshold voltage, change in the lifetime of charge carriers. Also in the article within the framework of changing other parameters of transistors the following calculations are carried out: change in the slope of the drain-gate characteristic, change in the leakage current in the drain circuit, thermal generation current, surface leakage current, change in input resistance.
