摘要 |
<p>The stand (1) has a mounting fixture (20) fixing test objects (10) with each other, and a mechanical load fixed to the test objects i.e. cylindrical bodies, by a pressure generating unit (30) through a hydraulic chamber. The pressure generating unit includes a piezo-actuator (31) and the fixture includes a heating element (23), where a temperature load is applied on the test objects. The mounting fixture is provided with a set of plate elements (21, 22), and the heating element is arranged between the plate elements, where one of the plate elements is turned towards the test objects.</p> |
