Failure analysis

Material testing and systematic failure analysis for rail vehicles according to VDI 3822

This includes, in particular, material tests and the investigation of damages. In addition to various test methods, we also carry out non-destructive tests in our test centre.

Fields of application

  • Investigation of damages, for example due to unsuitable materials, material quality, overload or wear
  • Material investigations for the raw-material qualification of metals, non-metals, plastics up to fibre composites and material combinations
  • Assessment of strength and reliability of various manufacturing and production processes including 3D printing


  • Systematic failure analysis according to VDI guideline 3822:
    • Determination of the primary damage mechanism
    • Derivation of causal influences
    • Remedial action and prevention of damage
  • Macroscopy and stereoscopy
  • Metallography / Materialography
  • Scanning Electron Microscopy (SEM)
  • Chemical and physical material analyses
  • Non-destructive testing methods:
    • Ambulatory metallography
    • Fluorescent dye penetration test (PT)
    • Fluorescent magnetic particle inspection (MT)
    • Computer tomographic component examination 2D/CT
