A Proposed Standard Round Compact Specimen for Plane Strain Fracture Toughness Testing

Abstract

A round, disk-shaped specimen is proposed as a standard K sub Ic test specimen for addition to ASTM Method E-399. The specimen is diametrically cracked, and it is loaded in the same general way as the existing standard compact specimen. Test and analyses are described which were performed to verify that the proposed round compact specimen and associated K solution are appropriate for a standard K sub Ic test. The use of the round compact specimen for other fracture tests is described.
