Crack-growth-rate Estimation on a Three-point Bend Specimen During Low-cycle Fatigue

Tryding, Johan LU (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.
