註釋
Early and incomplete results of a multilaboratory test program examining two procedures for measuring crack arrest toughness are presented. The program involves 30 laboratories, with each participant conducting 10 tests, including eight of a common heat of A533B steel. The preliminary results are encouraging. No special difficulties in applying the test procedures have been encountered and the test specimens are performing satisfactorily. The results appear to be quite reproducible. Crack arrest toughness values derived from the two procedures with a static analysis agree closely, but values calculated using a dynamic analysis differ by about 50 percent. A possible source of this discrepancy is identified.
