Mechanical-technological testing

What is meant by mechanical-technological tests?

In mechanical-technological test procedures, the behaviour of materials under certain mechanical stresses is examined. In addition to tests in the laboratory with standardised testing machines and test specimens, we also carry out operational tests with original components and systems as well as material tests using mechanical-electrical measuring sensors. The mechanical-technological tests in our laboratory can be divided into three main groups:

  1. Strength tests: In the course of strength testing, strength parameters (e.g. yield point, yield strength, tensile strength) and deformation properties (e.g. elongation at break, constriction at break) are determined. Depending on the test method, the material is subjected to various stresses (e.g. tension, compression, bending, shear, torsion) under specific time sequences (e.g. rapid, constant, abrupt, oscillating). The material characteristics are determined on test specimens with defined or standardised dimensions and under specified test conditions.
  2. Hardness testing: In hardness testing, the resistance of a material surface to plastic deformation by a standardised indenter is determined by precisely measuring its permanent indentation in the material surface. Depending on the test method, the indentation resistance is determined as the ratio of the test force to the surface of the indentation (Brinell hardness, Vickers hardness) or as the permanent penetration depth of an indenter (Rockwell hardness). In addition to these hardness testing methods with static force application, we also carry out methods with impact-type test force application (e.g. rebound hardness testing according to Leeb).
  3. Technological tests: Technological test methods are used to examine materials and components with regard to their manufacture, processing and further processing. The results are usually process-dependent, so that an exact specification of the test method, test object and test conditions is required. In our materials laboratory, we carry out tests in connection with joining processes (e.g. welded joints, soldered joints, adhesive joints) and tests of product forms (e.g. cast materials, forged parts, rolled products, deep-drawn sheets).
