Abstract:
Fitness for Purpose (FFP) analysis methods are more and more applied toassess the integrity of constructions. FFP analyses were carried out for
static and cyclic loaded components of nuclear and non-nuclear installations.
The structural integrity of those components is analyzed and assessed with
regard to the ASME criteria. The ASME evaluation requires a large amount of
mathematical and administrative calculations as a result of which in most
cases the overview of the applied method and the control of the method is
lost, in particular for components or parts thereof which undergo cyclic
loading in the elasto-plastic area for which a supplementary 'Simplified
Elasto-Plastic Analysis' is required. The visualization of the largest stress
variations in the construction, in combination with the Fatigue Curve of the
applied material, gives a very good impression of the possible damage and the
origin of assumed defects. By this, also non-experts can gain insight into
and control the applied linear rule of damage. 10 refs.
