MTS Bionix tabletop test system

The dynamic test system enables accurate, reproducible testing of fatigue life, fracture mechanics, tension, bending, torsion and compression of various materials. The axial-torsional system enables cyclic tests to be carried out to simulate the operation of a medical device under actual loading conditions. The proposed tests make it possible to assess the device in terms of its durability and wear.

parameters:

  • 0-25 kN for axial force
  • Force display accuracy 1 N
  • 250 Nm for torsion torque
  • Accuracy of torque indication 0.5 Nm

ME – 46 video extensometer

It is a system that enables a non-contact measurement of a specimen. 

Thanks to the very high resolution of the recorded image, it enables the properties of materials to be traced at very low strains.

The system is highly accurate, versatile and is ideal for non-contact strain measurements. The video-extensometer acts as a strain gauge by continuously measuring the distance between marked markers. Strain is calculated by measuring the distance between markers relative to the initial distance.

The minimum resolution achieved during measurements depends on the size of the measuring field.

DIC and microDIC digital image correlation system

Digital image correlation is a technique for measuring displacements and deformations in real time. The results are presented in the form of colour displacement and deformation maps, making it possible to verify the formulated numerical models. The measurements not only provide static images, but also the possibility of visualising the deformation process in the animation form. In addition to measuring the values of the parameters under investigation, this makes it possible to analyse the deformation process itself, including the observation of fracture processes, crack propagation and the destruction of various materials and structures.

System allows for:

  • measurement of displacements with an accuracy of 1 µm,
  • precise determination of mechanical parameters such as Young’s modulus E, Poisson’s number,
  • determination of selected mechanical parameters for different areas of the specimen during one strength test

Komora termiczna4

Four-camera digital image correlation system

Digital image correlation is a technique for measuring displacements and deformations in real time. The results are presented in the form of colour displacement and deformation maps, making it possible to verify the formulated numerical models.

The measurements not only provide static images, but also the possibility of visualising the deformation process in the form of animations. This gives, in addition to measurements of the values of the parameters under investigation, the possibility to analyse the deformation process itself including the observation of fracture processes, crack propagation and failure of various materials and structures.

Technical data:

  • measurement of displacements with an accuracy of 1 µm,
  • precise determination of mechanical parameters such as Young’s modulus E, Poisson’s number,
  • determination of selected mechanical parameters for different areas of the specimen during one strength test.
