Development and Application of Iron-based Shape Memory Alloys for Construction
建设工程用铁基形状记忆合金的发展与应用
This seminar starts with a short overview on different ongoing research topics (e.g., advanced structural materials, advanced simulation techniques, metal additive manufacturing, and wind turbines and bridges) at the Institute for Steel Construction, Leibniz University Hannover, Germany. The seminar continues with a focus on our recent works on the development and application of iron-based shape memory alloy (Fe-SMA), the so-called memory-steel, in construction. First, the studies on the material properties of Fe-SMA in terms of shape memory effect and superelasticity are discussed. Next, the use of Fe-SMA in prestressed strengthening of steel structures is explained, including the applications in strengthening of steel girders, connections, and fatigue crack repairs. Various strengthening solutions such as using mechanically anchored or adhesively-bonded Fe-SMA, as well as the studies on the behavior of the Fe-SMA-to-steel bonded joints, are discussed. The use and application of Fe-SMA for strengthening of a 113-years steel bridge has been explained. In addition, studies on the innovative application of the Fe-SMA as pipe couplers are presented. At the end, innovative ongoing research on the additive manufacturing of architected Fe-SMA (4D-printing) are discussed. At the end, different methods (e.g., CSC or Humboldt scholarships) to do a PhD or Postdoc in my group in Germany will be discussed.
