The paper presents the results of the research for the static and fatigue strength of specimens made of aluminum-based high-strength alloys В95 and 1163. Specimens of different thickness sized 220 mm х 36 mm with a hole in the middle with a diameter of 6 mm have been loaded by using INSTRON 8801 and 8802 testing machines. The total sample volume worked out 400 specimens. The fatigue tests were carried out at cyclic regular loading with a frequency of 5 Hz. For the estimation of the effect of single-shot tensile and compressive static peak loads have been applied in blocks. S-N fatigue curves for various configurations of loading blocks have been plotted based on the results of the fatigue tests, the influence of various loading blocks on fatigue life have been compared for samples of two aluminum alloys. © 2020 Latvia University of Life Sciences and Technologies.
