Abstract: An articulating fixture for the flexure testing of ceramics, having a lower structure for supporting the bottom of a specimen to be tested and an upper structure for placing a load into the top surface of the specimen. Each such structure includes at least one articulated cooperating assembly which allows rotation in the direction of the surface of the specimen whereby when the specimen is twisted, it will adapt to the twist and still properly apply the load to the specimen. In one arrangement, each of the structures includes two lines of pressure provided by two loading pins so that there are four such points in the fixture. In another arrangement, the upper structure includes one line of pressure provided by one loading pin, and the bottom structure includes two lines of pressure provided by two loading pins so that there are three such points in the fixture.
