Test tools

for compression

and bend tests

For the performance of compression and bend tests a multitude of test tools of different versions and dimensions as well as for different test load ranges are available.

The bending supports and dies for the different bending and folding tests are usually exchangeable. The adjustability of the support distance and the free height of the bending supports and dies allow 90° bend tests and bending-folding tests with angles of up to 180°.

Deformation transducers

Extensometers

For the extension measurement, measurement systems with different gauge lengths, test travels and resolutions are available:

• Extensometers with contact measurement for the manual attachment to the specimen

• Extensometers with contact measurement for the manual or automatic attachment of the feelers to the specimen

• Extensometers with noncontact, optical measurement with specimen marks attached on the specimen

The manually attachable, incremental measurement systems can already be used with the industrial testing machines of the standard line.

Motor-driven measurement systems are controlled automatically or by means of a manual control unit. The macro extensometer is particularly suitable for the determination of the proof stress as well as for the uniform elongation and for the strain at break. For the determination of the Young's modulus of elasticity a small test travel and a high resolution should be selected. The long-stroke and the noncontact extensometers, due to their low resolution, are only used for larger gauge lengths.

Reduction in width monitor

For the measurement of the change in width, particularly for the determination of the vertical anisotropy r (r-value) an extension module for the macro extensometer is used. With this module the change in width is measured with a high precision in 2 or 4 resp. in 1 or 4 cross-section levels.
