That article is about aviation hardware and the industry used bolt stretch for a long while in certain applications and then came up with special washers that indicated that the bolt had reached the point of plastic deformity. Such hardware is always single use.
That is the case today but such was not always the case as my Dad chose to point out when we did our first rebuilds back in the 1980s.
