Abstract
Lifetime assessment of dynamically loaded structures is essential towards decision support for quantification of lifetime extension and optimization of predictive maintenance. Fatigue failures can have catastrophic consequences, both social and environmental. Reliable prediction of fatigue failure will lead to a substantial reduction of operation and maintenance costs for players in different sectors. The core of our current research is the development of numerical tools for structural and fatigue analysis of welded steel structures. Using finite element modeling, stress concentrations in large structures can be located and quantified. A custom developed python framework is then used to estimate the remaining lifetime of the structure.
