High-Strength Steel and Advanced Materials

The main framework of the research group incorporates the use of advanced materials to ensure research-based results in the engineering design. The combination of experimental research and modelling of structural materials ranging from small-scale (material level) to full-scale (complete structures) is our common approach.

The use of advanced materials will not only lead a sustainable supply and use of raw materials for new structures but also prolong the service life time of elderly structures. Thus, the application will reduce carbon footprint and avoid additional costs for strengthening, demolishing and full replacement of such structures.

Within this concept, the structural use of steels and their alloys is of great interest for application areas such as in bridges, offshore structures, railway vehicles, and high-speed ships. In all these applications, joining is the major design criterion. However, in spite of the great advantages offered, the challenge of overcoming strength limits always remains. This is encountered especially when lightweight design is required. Therefore, the research group focuses on performance improvement methods by using various types of high-strength steels and their alloys to offer lightweight solutions for such structural design.
