Fatigue lifetime extension of large scale welded structures

Fatigue and lifetime analysis - Kris Hectors

The goal of this project is to develop robust numerical tools for lifetime prediction of large-scale welded steel structures, such as railway bridges, craneway girders and offshore jackets. Python scripting and finite element simulations are combined for hot spot stress evaluation of total life and multi-axial crack propagation analysis of remaining life. Using actual data from load and condition monitoring is essential towards decision support for quantification of lifetime extension and optimization of predictive maintenance.
