Abstract
A single ligament specimen is used to test the tensile properties in the short transverse direction of metal plate. A method of testing the specimen includes holding the specimen on one side of the ligament stationary and applying force to the other side of the specimen to elongate the ligament, and apparatus for implementing the method includes a fixture, a stationary clamp in the fixture, a movable clamp slidably mounted in the fixture, a load cell for measuring applied force to the movable clamp to elongate the ligament of the specimen, and a displacement transducer for measuring elongation.
