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 has 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.
