Warning: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in /home/kd10343/www.dyna-mess.de/modules/mod_select_menu/helper.php on line 89

Materials characterization

DYNA-MESS testing machines can be used for static and dynamic tests of many kinds of materials.

Static properties

Some examples of static properties:Prüfmaschine zur Messung von E Modul und Streckgrenze

  • Tensile strength
  • Yield point
  • Elasticity modulus (Young's modulus)
  • Hysteresis
  • Fracture toughness
  • ....

During the loading of a specimen to a certain load or deformation, the values are continuously recorded to draw a force/displacement diagram.

DYNA-MESS software automatically calculates the static properties and generates a report. For example the stiffness under different loads or displacements can be determined.

Tolerances can be defined by the user in order to stop the test if the testing parameters are not respected due to an abnormal behavior of the material to be tested.

Dynamic properties

Here are some examples of dynamic properties

  • S-N curve
  • Service life
  • Dynamic stiffness
  • Loss angle
  • Strength loss
  • ...

During a dynamic test, the specimen is subjected to a cyclic load that can be defined by the following parameters:

  • Amplitude
  • Frequency
  • Waveform
  • Oscillation position

The force and displacement values are used to calculate the dynamic properties. In addition to the hysteresis curve, different calculation methods are available.

The dynamic tests can be used as a single test (determination of the parameters at an operating point), a sweep test (parameters as a function of frequency and load) or as an endurance test (parameters as a function of the number of cycles and load).
