stress―strain curvesramberg-osgood curvetestsThe paper develops an expression for the stress–strain curves for stainless steel alloys which is valid over the full strain range. The expression is useful for the design and numerical modelling of stainless steel members and elements which reach ...
Material modelling Nonlinear stress–strain behaviour Stress–strain curves Stainless steel Tensile tests 1. Introduction Stainless steel is gaining increasingly widespread usage in a range of engineering applications. The material is characterized by a nonlinear stress–strain curve which differs from that ...
Refined Model for the Stress-Strain Curve of Austenitic Stainless-Steel Materials at Elevated Temperatures The stress-strain curves of stainless steel at elevated temperatures were given and the development laws in a large range of strain were revealed. The ... S Fan,R Ding,J Zheng,... - 《...

Duplex stainless steelSteelTensile strengthTensionPlastic deformationThere is a need for developing an accurate and united mathematical model representing tensile engineering stress–strain curves of duplex stainless steels and high-strength steels up to maximum load....
True stress–strain curves for cold worked stainless steel were obtained over a range of strains that included a large strain exceeding the strain for the tensile strength (post-necking strain). A specified testing method was used to obtain the stress–strain curves in air at room temperature. ...

In this paper, the material stress-strain response of stainless steel is first discussed as this is fundamental to developing an understanding of the structural response at the cross-section, member and frame levels. Constitutive models to reflect the rounded stress-strain response of the material ...
