商品描述

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 offshore structure with applications for welded joints. Using experimental quantification, this bridges the gap between material fracture resistance and cracked engineering structures' fracture resistance such as surface cracks in structural components. Ductile and brittle fracture assessment integrates physics-enhanced models into new engineering assessment approaches applicable to welded joints under combined high and low cycle fatigue loadings.

This book is essential as a textbook for graduate students and a reference for practicing engineers in structural, mechanical, and marine and offshore engineering.

商品描述(中文翻譯)

這本前沿的教材涵蓋了當前實驗方法，以量化非傳統樣本的斷裂韌性、評估延展性撕裂和脆性斷裂，以及估算在高低循環和組合作用下的焊接接頭的新方法。它還提出了一種數位雙胞胎方法，用於疲勞裂紋的尺寸測量和壽命評估，並以一個海上結構的例子展示焊接接頭的應用。通過實驗量化，這本書彌補了材料斷裂韌性與裂紋工程結構（如結構元件的表面裂紋）之間的差距。延展性和脆性斷裂評估將物理增強模型整合到適用於在組合高低循環疲勞載荷下的焊接接頭的新工程評估方法中。

這本書對於研究生作為教科書以及對於結構、機械和海洋及離岸工程的實務工程師作為參考資料是必不可少的。

作者簡介

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.
