The determining failure mechanism leading to recuced service life is most often fatigue.

Stressfield Oy is specialised in life time assessment of structures. This assessment can be done using traditional fatigue analysis or fracture mechanics based analysis.

Fatigue analysis can be done using different standards (EN, DNV etc.) or generally accepted research results or recommendations (IIW etc.).

Fracture mechanics analysis can be used also when strength can not be analysed using standards or recommendations (non classified details, weld root side fatigue).

Linked to service life analysis is an improvement of the structure. We give recommendations for structural improvements so that the desired service life can be obtained.
