DESCRIPTION
Technical Description
Using the tester, typical phenomena such as phases of varying creep rates or temperature-dependent creep behaviour can be demonstrated in a simple creep rupture test. To obtain acceptable creep rates at room temperature, flat lead and plastic specimens are used. The unit comprises a base plate, support pillar with adjustable end stop, transmission lever and load weight. To avoid placing bending loads on the specimen, the specimen holders are equipped with knife-edge bearings. With the aid of a transparent conditioning box with thermal storage elements, experiments can be performed above or below room temperature.
