Evaluation of a Method of Test for Plane Strain Fracture Toughness Using a Bend Specimen

Source

A task group of ASTM Committee E-24 conducted an interlaboratory test program on determination of KIc using the proposed “Recommended Practice for Plane Strain Fracture Toughness Testing of High-Strength Metallic Materials Using a Fatigue-Cracked Bend Specimen.”

Analysis of KIc data for an aluminum alloy and two high-strength alloy steels showed that laboratory mean values were within ±10 percent of grand mean values. Replication was generally satisfactory, although not as good as for smooth specimen tension tests.

Information obtained on fatigue cracking and other details of the procedure will be useful in planned revisions, leading to a standard method of test.
