PhD scholarship in Diagnosis and Prognosis of Fatigue Damage in Steel Structures using Multi-Fidelity Models and Virtual Sensing - DTU Construct

Opportunity summary

The Section for Structures and Safety at DTU Civil and Mechanical Engineering Department is looking for an ambitious, motivated and skilled PhD student eager to dedicate three years to the diagnosis and prognosis of fatigue damage in steel structures, with emphasis on steel bridges. Over the past century, steel has been the backbone of structures and infrastructures. Much of this built stock is reaching or has exceeded its design lifetime while being exposed to harsher operational conditions than originally designed for. Fatigue, where repetitive loads initiate and propagate cracks, is a key challenge in this aging era, undermining the functionality, safety and longevity of critical steel infrastructure. There is an urgent need to advance monitoring, diagnosis and prognosis methods that can reliably assess fatigue damage and predict remaining lifetime, enabling proactive maintenance strategies that extend service life and reduce CO2 emissions. Through this PhD scholarship, you will contribute to the development of a multi-component framework for reliable and computationally efficient fatigue diagnosis and prognosis of steel structures. Building on the group's es1 …
