The deviatoric part of the potential is defined by providing uniaxial, equibiaxial, or planar test data; while the volumetric part is defined by providing volumetric test data, defining the Poisson's ratio, or specifying the lateral strains on the uniaxial, equibiaxial, or planar test data.
Uniaxial tension test – Engineering Cheat Sheet
Jan 8, 2022 · Tension test, alternatively referred to as tensile testing or uniaxial tension test, is one of the most commonly used tests to determine important material parameters such as Young’s modulus, yield strength, ultimate strength, elongation at break, Poisson’s ratio, and Lankford coefficients (R-values).
Uniaxial Tension & Compression Input Data | Ansys Courses
How do you use uniaxial tension and compression data for rubber? You can use test data directly with the response function hyperelastic model. This does not require any curve fitting and will use the data exactly. You must separate and enter the uniaxial tension and compression data directly.

Data lines to specify uniaxial test data for defining the unloading-reloading response of the Mullins effect material model:
This report describes the test equipment, process, analysis, and data file formats for the 2020 Numisheet benchmark study tensile testing of the four materials associated with the Numisheet conference benchmarks.
Uniaxial tensile tests are routinely conducted to obtain stress-strain data for forming applications. It is important to understand the deformation behavior of test specimens at plastic strains, temperatures, and strain rates typically encountered in metal forming processes.
3.1.4 Fitting of rubber test data - Washington University in St. Louis
For Treloar's test data, when taking into account uniaxial, biaxial, and planar test data, the Ogden and Van der Waals forms give a closer fit than the polynomial forms. The Arruda-Boyce and Yeoh forms also provide an accurate representation.
Rubber Modeling Using Uniaxial Test Data | NIST
Jul 1, 2001 · In this paper we show the benefits of assuming a Valanis-Landel form for the strain energy function by comparing it to models available in ABAQUS.
Material properties: hyperelastic model for the rubber
Three different sets of test data—a uniaxial test, a biaxial test, and a planar (shear) test—are available. The data (shown in Figure 1 and tabulated in Table 1, Table 2, and Table 3) are given in terms of nominal stress and corresponding nominal strain.
