Fracture Assessment of Weld Joints of High-Strength Steel in Pre-Strained Condition
Applied Sciences, 2019 Unstable fractures tend to occur after ductile crack initiation or propagation. In most collapsed steel structures, a maximum 15% pre-strain was recorded, at the steel structural connections, during the great earthquake of 1995, in Japan. Almost-unstable
