Testing machine and testing method for samples or test bodies

摘要

In a testing machine for samples or test bodies having at least one coupling device for components of the testing machine which can be moved relative to each other, in which a fluid is provided for the coupling between the components, for the purpose of reliable and accurate control of the loading behaviour, it is provided that the fluid is an electro-viscous liquid and electrode regions (11a, 11b, 17a, 17b, 26a, 26b) adjacent to at least one flow channel and assigned to each other are allocated to at least one of the components and/or respectively to one and to the other component, the electrode regions having connections for the application of an electrical control voltage. <IMAGE>
