Crack growth under alternating loading
V. M. Tikhomirov Siberian State University of Means of Communication, Novosibirsk, 630049, Russia
Abstract:
Crack propagation under alternating loading is investigated. Relations between the growth rate of a fatigue defect and loading parameters and the expression for the stress intensity factor are derived for compression of a cracked solid taking into account the possible contact of the crack faces. A model for the deformation of a small region near the crack tip is proposed which allows one to formulate the conditions of residual opening of a growing fatigue crack. The experimental data obtained in tests of steel samples are compared with the results of calculation using the developed procedure.
Keywords:
alternating loading, fatigue crack, initial crack opening, stress intensity factor.
