Mechanical Testing Laboratory

The mechanical testing laboratory specialises in static, cyclic and fracture mechanical testing of various metallic materials, metal-ceramic composites, cemented carbides, etc.

Our special focus is on:

  • Determination of mechanical material parameters (hardness, yield strength, strength, ductility)
  • Determination of cyclic material parameters (S/N curve, fatigue strength)
  • Determination of fracture mechanical material parameters (fracture toughness, J-Integral, da/dN-curve)
  • Determination of material data for finite element simulation (constitutive laws)

The range of services extends from tests in accordance with international standards to tests on high strength and britte materials. If required, new testing methods are developed, which are offered as a service to our customers.
