Advanced numerical analysis and design requires knowledge of the stress–strain relationship of the alloys over a full range of the stress–strain curves. This paper provides a detailed review of the evolution of the stress–strain models of stainless steel, in literature....
strength,the hardening strain at the onset of strain hardening and the ultimate strain corresponding to the ultimate strength of structural steel at high temperatures.Compared with ASCE and EC3 models,this proposed stress-strain model is generally in better agreement with measured stress-strain curves....
A standard uniaxial tensile test, which establishes the engineering stress-strain relationship, in general, provides the basic mechanical properties of steel required by a structural designer. Modern numerical analysis techniques used for analysis of large strain problems such as failure analysis of steel...
S–N curve of spot-welded specimens with initial correction parameter r = 0.5 Full size image In fact, spot welding is widely used in structures of railroad vehicles and the bodies and main components of automobiles. Automobiles are mainly made of thin-walled, high-strength steel and railr...
Cyclic stress-strain behavior of structural steel with yieldstrength up to 460 N/mm doi:10.1007/s11709-014-0245-yFrontiers of Structural & Civil EngineeringChen, YiyiSun, WeiChan, Tak-Ming
Once fabricated, samples are tested in uniaxial compression using a nanoindentation device outfitted with a flat tip, and a stress-strain curve is obtained. The methodology can be used to examine the plastic response of samples of different sizes that are from the same bulk m...

Recently, much excellent experimental work has been done on the behaviors of structural steel under uniaxial cyclic loading [20], [21], [22]. While the stress-strain relationship, as well as the damage evolution process, has been analyzed, the methods to quantify damage are still limited. In...
