Material testing machines

Brief Description:

The BUP 1000 sheet metal testing machine from ZwickRoell is applied when characterizing a wide variety of sheet materials in terms of formability and strength. Its modular design allows different tools to be installed, e.g., tools designed for the Nakajima, Marciniak, or hydraulic cupping tests. An investigation of ultra-high-strength materials is possible due to the maximum punch and sheet holder force of 1000 kN. By coupling with the optical measuring system ARAMIS 4M from GOM GmbH, it is possible to record tests time-continously and analyze the occuring strains.

Brief Description:

The ZwickRoell material testing machine can be used universally for the testing of materials. Its modular design offers maximum flexibility and expansion options. Force measurement for the stress determination occurs on load cells mounted in the machine, which can accommodate a maximum force of 200 kN or 20 kN. So-called DUPS control the machine via electronics and the TestXpert II software.

Brief Description:

We developed this measuring apparatus especially to determine the material-specific Seebeck coefficient, which describes the thermoelectric behaviour of a material. Based on the integral measurement method, the temperature difference between the two ends of a test sample is increased continuously from 0 °C to 700 °C, and the resulting thermoelectric voltage is determined. The material characterization is relative to the reference material platinum and bases on both the heating and cooling curves. In principle, the unique set-up allows the investigation of all electrically conductive pure elements, material alloys and coatings.

Technical Specifications:

Main Areas of Application:

• Material chracterization (determination of the Seebeck coefficient)
• Calibration of tool-workpiece thermocouples

Brief Description:

The acoustic test bench bases on the pulse excitation method and is used to measure Young's modulus, shear modulus, and transverse contraction number of cuboid specimens. An impulse is applied at a defined point on the specimen using a hammer attached to an electric motor, causing it to vibrate. A microphone is required to measure the resulting vibrations transmitted from the sample to the environment. It is then possible to calculate the specimen's elastic constants with a frequency analysis of the signal.

Main Area of Application:

• Determination of Young's modulus, shear modulus, and Poisson number
