Samples of the
material allow
conclusions about
the reasons for
the failure
|

Component failure can be caused by incorrect selection of materials,
incorrect dimensioning, manufacturing defects or unacceptable loads. If
a component has failed or been damaged, a defect in-depth analysis can
identify the reasons for the failure.
The mechanics of the damage can be deduced from the point in the component
where the break occurred, the characteristics of the material at the cross-section
of the break, the geometry of the part that failed, the point where the
defect started and the surface of the fracture itself. We have our own
scanning electron microscope with connected EDAX for materials chemical
analysis.
In order to calculate the load parameters that caused the damage, we use
pipework programs (static and dynamic analysis) and ANSYS Finite Element
(FE) programs. When required, we commission examinations of original material
samples under operating conditions (load, temperature).
Knowledge of the causes of the failure or damage is used as a basis for
recommendations such as a change in the selection of materials, manufacturing
processes, geometry or loading in order to prevent the defect from reoccurring.We
take temperature and strain measurements for our customers for the purpose
of optimizing components and designing components and systems. With the
ANSYS program we can simulate and analyze elastic and elasto-plastic stresses
(including contact problems) and calculate temperature fields.
