Abstract

A ring-shaped clip-on displacement gage for fracture mechanics testing is described. The novel design of this gage offers superior sensitivity and operating conveniences compared with the conventional double-cantilever beam type gage referenced in ASTM fracture test standards. The construction of ring gages for room temperature and cryogenic applications is discussed.
