This cutting-edge text covers current experimental approaches to quantify the fracture resistance in non-conventional specimens, assessment of ductile tearing and brittle fracture, and new approaches to estimate welded joints under high and low cycles and combined actions. It also presents a digital twin approach for the fatigue crack sizing and life assessment, along with the example of an... Read more

Biography

Dr. Liuyang Feng is currently a Full Professor at the School of Aeronautics, Northwestern Polytechnical University, specializing in structural integrity assessment. He is a key member of the laboratory. He earned his first-class honours degree from the Department of Civil Engineering at Huazhong University of Science and Technology in 2014. Subsequently, under the supervision of Prof. Qian Xudong, he completed his PhD in 2019 at the Department of Civil Engineering, National University of Singapore, focusing on energy-based approaches to low-cycle fatigue in welded joints. From 2019 to 2023, he served as a Research Fellow, collaborating with accomplished researchers and professors. Over the past decade, he has integrated his expertise in fatigue research with non-destructive crack sizing methodologies, reliability analysis, and digital twin simulations. He has published more than 30 journal papers across these fields..

Dr. Xudong Qian is an Associate Professor and Director of the Centre for Offshore Research and Engineering and of the Centre for Advanced Materials and Structures at the National University of Singapore. He is a member of the ASTM technical committee on Fatigue and Fracture.
