Constitutive Model and Fracture Criterion of Q345 Steel Welded Joints

open access: yesComplexity, Volume 2022, Issue 1, 2022., 2022
Welding joint is a key component in steel structure engineering, which is often subjected to complex stress and becomes the weak link of building structure, and different fracture modes may appear under different stress. In this study, the ductile fracture of Q345 steel welded joint was investigated by selecting the base material and heat‐affected zone
