The contribution presents the detail discussion on various problematic aspects of utilization of both fracture mechanics based methodology and NDT technology to conduct the assessment of failure of components. Consequently, it shows a software tool concerning Probability of Detection – Probability of Sizing Concept, which allow to bring both methodologies (Fracture Mechanics and NDT ) together and to meet in a joint approach. The contribution introduces in the application of one software approach, which allows modeling and simulation of real scenarios in detail, based on a variety of properties of different relevant materials from practice.

Praca ta przedstawia szczegółową dyskusję na temat różnych aspektów problematyki jednoczesnego wykorzystania metodyki opartej na mechanice pękania i technologii badań nieniszczących (NDT ) do przeprowadzania oceny i predykcji uszkodzenia komponentów. W konsekwencji, przedstawiono oprogramowanie narzędziowe odnoszące się do koncepcji prawdopodobieństwa wykrycia (Probability of Detection– Probability of Sizing), które pozwalają na połączenie obu metodologii (mechaniki pękania i NDT ) i działanie w ramach wspólnego podejścia. Praca przedstawia implementację w ramach oprogramowania podejścia, które umożliwia modelowanie i szczegółową symulację rzeczywistych sytuacji, przy uwzględnianiu wielu właściwości różnych materiałów używanych w praktyce.
