stainless steelstress―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...
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,... - 《...

Dimensionless charts are derived from this formula for determining the stress-strain curve, the tangent modulus, and the reduced modulus of a material for which these three parameters are given. Comparison with the tensile and compressive data on aluminum-alloy, stainless-steel, and carbon-steel ...
A new J-integral estimation procedure, referred to as the reference plastic slope method, was developed in order to provide J-integral solutions for cold worked and non-cold worked stainless steels. In the reference plastic slope method, J-integrals for bi-linear stress–strain curves were used...
Modified stress-strain relation for FCC metals and alloys The flow curve of some metals in the region of uniform plastic deformation can be expressed by the Ludwik model, σ= K ∈ n . For stable austenitic stainless steels and other face-centered-cubic (fcc) metals with low stacking fault ...
True stress–strain curves were obtained for irradiated 316L stainless steel by a tensile test and by a curve estimation procedure. In the tensile test, th... M Kamaya,Y Kitsunai,M Koshiishi - 《Journal of Nuclear Materials》 被引量: 3发表: 2015年 Tensile Test Based Material Identification...
Diagram of the stress-strain curve. Stress-strain diagrams is commonly used to analyze the behavior of a material throughout its loading until failure. Each material exhibits a unique stress-strain pattern that design engineers can use to extract important mechanical properties such as strength, toug...
In the cyclic stress–strain curve, the total strain has been used for the abscissa. If the loop half-width at zero stress had been used, the CSSC would be plotted for the plastic strain.Courtesy of M. R. Mitchell and ASM International. The cyclic stress–strain curve can be compared ...
