The Mechanism of Critical Strain of Serrated Yielding in Strain Rate Domain
Chinese Physics Letters, 2016 The mechanism of the critical strain of serrated yielding is studied via tension tests at various strain rates. Before the critical strain, it is deduced that dislocations are not pinned at high strain rates, and dislocations at low strain rates are pinned but cannot escape.

Numerical simulation on strain capacity of welding joint of X80 pipeline with root welding crack
You-qi chuyun, 2022 Automatic welding technology is widely used in the field welding of large-diameter and high-grade steel pipelines in China. Welding defects such as misalignment and cracks caused by various factors have seriously affected the deformation and bearing ...

Critical Infrastructures: Reliability, Resilience and Wastage
Infrastructures, 2022 By 2050, according to the UN medium forecast, 68.6% of the world’s population will live in cities. This growth will place a strain on critical infrastructure distribution networks, which already operate in a state that is complex and intertwined within ...

Prediction of steel flow stresses under hot working conditions
Materials Research, 2005 An austenitic stainless steel was deformed in torsion over a temperature range of 900-1200 °C using strain rates of 1, 5 and 10 s-1. The stress vs. strain curves determined were corrected for deformation heating and the flow stress was found to rise ...

A critical assessment of theories of strain gradient plasticity [PDF]
Acta Materialia, 2009 Theories to extend plasticity to the micron scale have been in existence for over a decade, complemented by a growing body of experimental data. Here, materials and mechanics aspects of two prominent strain gradient theories of plasticity, due to Nix and Gao and to Fleck and Hutchinson, are assessed within the context of simple bending.

Criticality in Vibrated Frictional Flows at a Finite Strain Rate [PDF]
Physical Review Letters, 2016 We evidence critical fluctuations in the strain-rate of granular flows that are weakly vibrated. Strikingly, the critical point arises at {\em finite} values of the mean strain rate and vibration strength, far away from the yielding critical point at zero flow rate.
