Device and method for performing compression tests on specimens to characterize materials and corresponding specimens

摘要

The invention describes a device (1) for carrying out compression tests on preferably cube-shaped specimens (2) for characterizing materials, comprising four pressure tools (5) which are offset from one another at 90 ° and which are opposite in pairs with respect to the specimen (2) can be moved relative to one another and each pair of pressure tools (5) exerts a monoaxial pressure on the sample body (2). Here, of the pressure tools (5) assigned to one another in pairs, at least one pressure tool (5) can be moved along a linear movement path (3) and the pressure tools (5) have pressure surfaces (2) to interact with the surfaces of the specimen (2) to be pressurized. 6), which are each aligned at an angle of 45 ° with respect to the linear movement path (3) of the associated printing tools (5).
