Abstract

The paper presents the results of a study of the mutual influence of concentrators of the "dent" type, made by a hemispherical indenter with a diameter of 25 mm to a depth equal to the thickness of the sheet, and a "hole" with a diameter of 4 mm in thin 1.5 and 3.0 mm thick aluminum alloy 1163AT on static strength and fatigue. The presence of a dent did not lead to a decrease in static strength, while the combination of "dent + hole" concentrators reduces the strength to ~ 8% regardless of the location of the hole in the dent. The position of the hole relative to the center of the dent practically does not affect the slope of the fatigue curve, while the displacement of the hole from the center to the edge of the dent leads to a decrease in durability.
