In this work, the microstructure evolution characteristics after 3% pre-strained at different strain rates are elaborated to reveal effect on mechanical behavior of dual-phase steel. The results showed field simulated by representative volume element model shows obvious heterogeneity, and degree localization intensifies with increase rate. There is sufficient time complete dynamic transition among geometrically necessary dislocations (GNDs)-low-angle grain boundaries (LAGBs)-middle angle...
Abstract The fracture analysis of girth‐welded pipes is a vital link in the integrity assessment oil and gas pipelines. However, effect welding residual stresses (WRS) on load‐carrying capacity pipe with crack remains unclear. In this study, based WRS simulation results verified by full‐scale experiment, dynamic finite element model could describe process inner surface girth weld considering was developed Gurson–Tvergaard–Needleman (GTN) damage model. Based model, behavior under tensile load...
Abstract There is much controversy in using laboratory specimens to predict the fracture behavior of large industrial constructions because their different constraints. Although several parameters have been proposed characterize constraint effect, there are still some limitations. To address this issue, a novel unified characterization parameter based on critical crack tip opening angle (CTOA C ) defined. Firstly, calibrated finite element technologies for simulation static and dynamic used...
