Damage Analysis

Failure analysis

Identifying damage mechanisms, determining damage causes and deriving necessary and practicable measures for damage prevention.

A useful tool to improve components systematically.

As shown in practice, every error that can theoretically happen will eventually occur and repeat itself if nothing has been done to counteract the causes of the error. Therefore, it is constructive to determine error causes systematically and to remedy them vigorously.  

 

Damage undoubtedly constitutes an annoying event. Therefore, any failure or damage, accompanied by a systematic damage analysis, should be taken as an opportunity to achieve meaningful and targeted improvements.  

 

The frequently practised methods of trying to prevent future failure through snapshots or time-consuming trial and error operations often lead to misdirected, incorrect, delayed, excessive and therefore expensive measures. A systematic failure analysis on the other hand can provide valuable information about component properties that are of central importance to a product's service life and need to be improved to prevent a recurrence of the issue. A systematic failure analysis can help avoid inappropriate, impracticable or excessive measures.

Take advantage of our experience and expertise:

  • Professional, unbureaucratic and quick help in problem situations
  • Suggestions for targeted, comprehensive and practicable corrective measures
  • Working together to outline optimum production processes
  • Competent support with complaints
  • Basis for optimisation measures and further developments

Systematics of failure analysis at RÜBIG:

  • Assessment of material, process or case-induced failure or damage of metallic components and tools, determination and restriction of the causes and derivation of suitable, appropriate and practicable prevention measures in the case of:
  • Tears and breaks
  • Wear and tear
  • Corrosion
  • Combined damage mechanisms, e.g. breaks caused by hydrogen embrittlement, stress corrosion cracking, surface fatigue caused by fretting corrosion, etc.
  • Our failure reports and expert reports are comprehensible, clear, traceable, precise as well as solution and practice-orientated
  • Assessment of material and heat treatment conditions of defective components and tools:
  • Target/actual comparison with the specifications (conformity test)
  • Assessing unknown components to see whether the determined conditions of material and heat treatment are typical, reasonable and suitable for the application
  • Assessment of defects in the production of steel and raw material production
  • Assessment of production-induced errors, e.g. friction martensite, grinding burn, forging and casting errors, welding errors, eroding errors, insufficient heat treatment
  • Assessing whether defects or deviations are part of a typical variability or whether the component’s strength or load capacity was actually reduced and contributed to failure in this specific case
