    Material testing

    The characteristic values of materials are determined both statically and dynamically. DYNA-MESS testing machines can be used for both types of testing from a few Newtons up to the meganewton range. We are guided by global guidelines and standards as well as individual customer specifications.

    We are DYNA-MESS. Test Systems.

    Tests

    Standardised sample forms


    In contrast to component and part testing, materials are generally tested on standardised specimens. A classic example of this are tensile tests on metallic specimens in accordance with EN 6892.


    In quasi-static tests – often referred to as “static tests” – the load is applied so slowly that dynamic effects do not play a role. Typical results of quasi-static tests are, for example

    Quasi-static tests

    • Tensile strength Rm
    • Yield strength ReH/ReL
    • E-modulus E
    • Elongation at break A
    • Spring stiffness C
    • …

    Dynamic tests

    In dynamic tests, a – usually cyclical – load is applied with a corresponding test frequency. These can be threshold load tests in the tensile or compression range as well as alternating load tests with tensile and compression components.

    Dynamic tests are used to determine characteristic values on the one hand and to test service life on the other. Typical dynamic characteristic values are e.g.

    • Wöhler curve
    • Service life
    • Hysteresis curve
    • Dynamic stiffness Cdyn
    • Loss angle φ
    • Loss work Wverl
    • …

    Individual testing and endurance testing


    While the static and dynamic characteristic values of the materials are determined in individual tests, the long-term behaviour under dynamic load is examined as part of endurance tests. The continuous data recording of the DYNA-MESS testing software documents both the running-in effects at the start of the test and the change in the test specimen during the test period.

    Matching accessories

    In order to fulfil the requirements of the various standards, we offer additional accessories such as clamping fixtures, special and standard-compliant devices, tactile or non-contact extensometers in longitudinal and transverse direction, temperature control devices …

    Application example: Screws up to M 72

    Fasteners used in wind power technology, for example, place high demands on testing technology. Bolts with a size of up to M 72 can be loaded with forces in the meganewton range and pulled until they break. The testing software ensures that a tensile test is carried out in accordance with EN 6892, in which all parameters such as modulus of elasticity, tensile strength, yield strength, etc. are determined.
