concreterate effectstress–strain curveuniaxial stressvariabilityConcrete is a typical rateヾependent material, and a direct tensile test is the most effective method by which to investigate its tensile performance. In this study, an additional loading device for direct uniaxial tensile tests was ...
In order to obtain the tensile stress-strain curve of steel fiber reinforced reactive powder concrete( RPC),axial tensile tests on reactive powder concrete were completed using a self-designed equipment. The complete tensile stress-strain curve of RPC with different volume fraction of steel fiber( ...
One representative direct tension stress–strain curve for each of the six strain rates investigated in this study is shown in Fig. 2(a). A zoomed view of this figure showing the elastic region, as well as the inelastic stress–strain curve up to 0.2% strain is shown in Fig. 2(b). ...

The process of designing Strain Hardening Cementitious Composites (SHCC) is driven by the need to achieve certain performance parameters in tension. These ... EB Pereira,G Fischer,JAO Barros - 《Cement & Concrete Research》 被引量: 60发表: 2012年 SIMULATION OF THE TENSILE STRESS-STRAIN EHAVIOR...
A uniaxial stress/strain curve is represented empirically by a modified Ramberg-Osgood equation ∊=(σ/E) + (σ/σo)m. Firstly E is extracted then σo and m are determined from two points on the experimental curve. These values are improved iteratively by a least squares fit using all ...
2The strength of columns with yield-tensile ratios up through about 0.95,based on measured properties,can be reasonably predicted with the present relationships that are used for other steels. The material stress-strain curve must be reasonably linear,with the proportional limit in a tension test ...
Tensile strain softening curve is very important in crack analysis for concrete structures. It can be obtained from direct axial test, but the test machine... T Li,X Xu,X Liu - Asce Aerospace Division Conference on Engineering 被引量: 0发表: 2012年 Prediction of concrete tensile strength fro...
