| Abstract | Steel members subjected to extreme loading conditions (e.g. earthquakes, hurricanes, support settlements, industrial plant shutdown) undergo large deformations, associated with widespread yielding, leading to fracture, either due to monotonic loading or ultra-low-cycle fatigue (ULCF). This project aims at developing innovative computational methodologies that simulate steel material fracture under ultra-low-cycle fatigue following a multiscale approach, with calibration from both micro and macroscale testing. The project focuses on base steel material only and on pipeline applications. Project results (experimental/numerical), will be used to develop design guidelines for strain-based ULCF design, amending current fatigue design practice (EC3, EC8). | ||
