Device for off-axis tests of anisotropic materials

摘要

The testing device has jaws consisting of two parts. One part (351,361) has the heads (32,33) of a composite test piece (30) bolted to it and is furnished with a slot (353,363) of circular profile about transverse axes (R) at the head of the test piece. The second part of the jaws consists of a roller (354,364) mounted in bearings in a U-shaped housing. The housing is attached to the test machine through a socket and tube secured by a gudgeon pin and the roller rolls in the slot without slipping.
