Fatigue and Fracture Assessments for Welded Joints - From Physics-Based Approaches to Digital Twins

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 cycle 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 fracture resistance for realistic cracks in engineering structures 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 high and low and combined cycle fatigue.
This suits as a textbook for graduate students and a reference for practising engineers in structural, mechanical, and marine and offshore engineering.
