摘要： Tensile testing device, which measures the strain for a tensile testing specimen (24) by means of the relative displacement of the fastening means (2, 14), as a result of that the attachment of the tensile testing specimen (24) is performed in such a manner which is independent of the applied tensile testing force. Furthermore, the device provides a contact-free dimension measurement (26, 27) of the tensile testing specimen (24) simultaneous to the tensile testing procedure. The device enables at the same time a compensation of measured values for machine strain and friction forces, and the pulling speed in the tensile testing procedure is controllable, depending in the appearance of the tensile test curve. Moreover, the maximum tensile stress, various standardised strain measures and the fracture area may be calculated.
