STRESS–STRAIN CURVES FOR FATIGUED RUBBER
Canadian Journal of Research, 1950It is shown that with natural rubber, vulcanized to soft "gum" rings, extension curves after the first are in two parts, and that the second part does not develop except after severe previous extensions.With molded rings, stretched initially a few per cent short of rupture, these effects are very marked, and the fifth extension curve is in two clearly

Isochronous Stress-Strain Curves for Alloy 617
Volume 1: Codes and Standards, 2019Abstract Alloy 617 is a high temperature nickel based material that could have significant design advantages when compared to austenitic steels in very high temperature reactor applications. Several high temperature design methods, including Section III, Division 5 of the ASME Boiler & Pressure Vessel Code, require a model for the ...

Some detailed stress-strain curves for rock
Journal of Geophysical Research, 1965Detailed axial stress-strain curves for the compression of free and confined cylindrical specimens of an Australian sandstone and a South African quartzite are presented. These show that the secant moduli of minor stress cycles, within a major stress cycle, are significantly greater than either the secant or tangent modulus of the major cycle.

Complete Triaxial Stress-Strain Curves for Concrete
Journal of the Structural Division, 1982A method to predict the ascending and the descending parts of stress-strain curve of concrete subjected to triaxial compressive stresses is presented. The proposed analytical stress-strain relationship depends on the values of the three principal stresses and strains at the ultimate compressive strength.

Modeling Stress Strain Curves for Nonlinear Analysis
Materials Science Forum, 2008Methods of modeling stress strain curves for nonlinear stress analysis are discussed in order to obtain comparable results between different finite element analysts and between different versions of designs. The most common method for modeling stress strain curves is to use Ramberg- Osgood equation. For materials with significant discontinuous yielding,

Stress Strain Curves from the Ring Test
1975A new procedure for the establishment of stress strain curves from the ring test is described. The underlying upper bound theory, due to Avitzur, has been used to produce a very practical calibration chart for easy reduction of experimental data. The validity of the technique has been assessed by conducting ring tests and tensile/compression tests on ...

Derivative stress‐strain curves of polyacrylonitrile fibers
Polymer Engineering & Science, 1969Abstract Derivative stress‐strain curves at constant strain rate for polyacrylonitrile copolymer fibers have been obtained by simple modification of conventional tensile testing apparatus. These derivative curves, considerably more complex and eventful than stress‐strain curves, have been interpreted as direct records of changes ...
