Crack-growth-rate Estimation on a Three-point Bend Specimen During Low-cycle Fatigue
(1991) In Experimental Mechanics 31(1). p.42-46- Abstract
- The ratio of the change of the clip-gage measured crack-opening displacement of a three-point bend specimen to the change of the displacement at the point of application of the cyclic load is shown to vary linearly with the ratio of the crack length to the specimen height. With the aid of this relation, the crack-growth rate is obtained by numerical
differentiation of the crack length with respect to the number
of load cycles. A clip-gage correction factor is introduced in
order to compensate for the use of external edges to position
the clip-gage during the experiment.
