Elsevier Editor “Structures”.
嘉宾简介
Elyas Ghafoori is a Full Professor of “Steel, Composite and Lightweight Construction” and the Executive Director of “Institute for Steel Construction” at the “Leibniz University Hannover” (among top 9 technical universities, TU9, in Germany). He is the managing Director of “Test Centre Support Structures (TTH)”, Hannover, and a scientific leader at “Fraunhofer Wind Energy System (IWES)”. He is also a guest Professor at Tongji University. He worked in the past for ETH Zürich and Empa Dübendorf, in Switzerland. He is an editor in Elsevier journal of “Structures” and an Executive Member of IIFC. Prof. Ghafoori´s research is on four topics: advanced structural materials (e.g., shape memory steels, FRP composites and adhesives), advanced simulation techniques (e.g., topology optimizations and machine learnings), robotic and additive manufacturing (robotic welding and wire and arc additive manufacturing, WAAM), support structures for wind turbines (e.g., welded, bolted and grouted joints) and bridges (e.g., fatigue strengthening of lifetime extension).
报告简介
This lecture 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 lecture 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.
