On May 7, 2020, the “Innovation Base of Earthquake Engineering Comprehensive Simulation” held a “Cloud Report”. Dr. Xudong Qian, an associate professor from the Department of Civil and Environmental Engineering, National University of Singapore, presented a report named “Fatigue of Welded Joints - Enhanced Weld Details and Assessment”.
This report was hosted by Associate Prof. Jie Xu from the School of Civil Engineering. Prof. Qinghua Han, Dean of the School of Civil Engineering, attended the report and delivered a welcome speech.
During the report, Dr. Xudong Qian introduced the simplified weld protocol with equivalent strength. He also shared the methods of enhanced fatigue assessment, which includes the effective notch stress method and low cycle fatigue assessment.
The audience at the meeting learnt about two simplified approaches to calculating the effective notch stress, which are the energy approach to assessing low-cycle fatigue and a rapid approach to estimating the S-N curve for low-cycle fatigue. After the report, Dr. Qian and the audience conducted an online discussion on related issues.
A total of 143 teachers and students from Tianjin University, Tianjin Chengjian University, Hebei University of Technology, Nanjing Tech University, Hebei University of Water Resources and Electric Engineering participated this “Cloud Report”, including 12 teachers, 81 graduate students, 18 international students, and 32 undergraduate students.
Dr. Xudong Qian is currently the Group Head of the Structural and Offshore Engineering, and the Director of the Centre for Advanced Materials and Structures NUS. He received his Bachelor’s Degree (1st Class Honors) and PhD in Civil Engineering from NUS in 2000 and 2005, respectively. Prior to joining NUS as a faculty member, he worked as a post-doctoral research associate in the Department of Civil and Environmental Engineering, University of Illinois at Urbana Champaign (UIUC). Qian’s research interest focuses on experimental fracture mechanics, fracture and fatigue assessment for large-scale structural components, welded connections, steel-concrete-steel composite structures, and polymer composite materials for deep-water applications. Dr. Qian has been serving with a membership in different Technical Committees for the International Ship and Offshore Structures Congress since 2009. He is also a member of the technical committee in American Society of Testing and Material E08 – Fatigue and Fracture, and F42 – Additive Manufacturing Technology.
