This model should be applied to specific measured data from stress-strain curves for three strain rates at the temperature range from 1023 to 1273 K. The specimens were made of 9Cr steel. The curves were obtained by processing flat specimens of 10 x 15 x 20 mm in the Gleeble compression ...
Both ascending and descending portion of the stress±strain curves are a?ected by the addition of steel-?bers. However, the signi?cant e?ect is noticed in the descending portion of the stress±strain curve. The slope of the descending part of the stress± strain curve, decreases with ...
The second strain hardening exponent was denoted n0.2,1.0. A further two-stage model was also proposed by Gardner et al. [10] for application to stainless steel material modelling in fire. In the proposal, the second stage of the curve passed through the stress at 2% total strain, since ...
Steel-fiber reinforced concrete is increasingly being used day by day as a structural material. The complete stress–strain curve of the material in compression is needed for the analysis and design of structures. In this experimental investigation, an attempt has been made to generate the complete...

The so-called stress-strain curve in engineering is usually the nominal stress-strain curve.However,this kind of curve is only approximate,which only provides a reference to actual engineering problems.The true stress-strain curve of the widely used metal material-Q235 was obtained,through the expe...
According to the experimental true stress-logarithmic strain curves, the stress-strain curves of steel sheet vary with the stress state, and the strain-hardening exponent become larger when the load ratio is near the ratio 1:1. The contours of experimental yield loci for two steel sheets from ...
Such a relationship can be limned for every material. If we were to widen our scope beyond ductile and brittle materials, we’d be surprised to find materials such as plastics that don’t even have a fracture point. However, its proportional limit is negligible. On the contrary, steel, wh...
