At the invitation of our college, Associate Professor Qian Xudong from the National University of Singapore (NUS) delivered an academic lecture titled A Digital Twin Approach to Size Cracks in Welded Joints in the Lecture Hall of the Comprehensive Building on Xiaozhai Campus on the morning of October 30, 2023. The lecture was hosted by Associate Professor Liao Fangfang from the School of Civil Engineering, and a number of teachers (including Professor Nie Shaofeng) as well as more than 30 postgraduate students from the School of Civil Engineering attended the event.
During the lecture, Associate Professor Qian Xudong first introduced practical non-destructive testing (NDT) techniques for measuring crack sizes in welded joints, such as alternating current potential drop (ACPD) and phased array ultrasonic testing (PAUT). He also presented recent efforts to improve the accuracy of crack sizing through image processing and the development of reference-free methods. Based on the results of NDT, he shared the latest physics-informed and data-driven methods for sizing surface cracks with complex shapes in welded connections. In addition, the lecture also covered the application of digital twins in large-scale offshore structures.
At the lecture venue, teachers and students showed great interest in the content and engaged in in-depth discussions and exchanges with Associate Professor Qian Xudong.
