Abstract
The results of the creep tests with extension and torsion of tubular specimens made of D16AT and AD1 aluminum alloys, which were earlier obtained at the Institute of Mechanics, Lomonosov State University, were analyzed theoretically. Experimental data obtained with the author’s participation imply that a sharp increase in creep rate is observed under certain conditions when a vibration stress of small amplitude is added to the static stress. This effect (vibrocreep effect) is manifested only if the form of the stress state under the common action of static and dynamic stresses differs from the form of the static stress state. In this case, as the duration of the applied vibration stress increases, the vibrocreep effect gradually weakens.
