DOI: 10.1016/j.ijfatigue.2019.105214
Abstract: Abstract When a cracked shaft rotates, the crack contained in it progressively opens and closes during a revolution. Accordingly, the behavior of the shaft becomes nonlinear. In this paper, the propagation of concave semi-elliptical shaped… read more here.
