Measuring elastic-plastic fracture mechanics parameters

As in linear-elastic fracture mechanics, specimens in elastic-plastic fracture mechanics are also standardised. An initial crack is produced in the same way by cyclic loading. The values of the J integral for crack propagation, Jc and J, are read off the Jr crack-growth resistance curve, so there is no need to perform additional experiments. [Pg.163]

We will now discuss the procedure using the example of a CT specimen (figure 5.14(b)). The specimen is loaded using displacement-control, and a load-displacement curve is measured. The resulting graph will look like the one in figure 5.23. The area beneath the curve corresponds to the work done [Pg.163]
