After the input shown in figure 6 is finalized, Abaqus will perform the material evaluation. Relevant curves will be generated per test type (in the test setup tab-picture 6). The produced curves based on exemplary data are shown in figures 7,8 and 9 for uniaxial, biaxial and planar test data respectfully. Figure 7: Uniaxial fit. Figure 8 .
Numerical Simulation Analysis of Uniaxial Compression Damage of Reinforced Concrete Columns Based on ABAQUS May 2023 Highlights in Science Engineering and Technology 51:113-118 Subsequently, based on the geometric dimensions of the specimens and the test boundary conditions, the finite element software ABAQUS is utilized to construct a uniaxial compression numerical model. The present study aims to determine a suitable constitutive model dependent on strain energy potential which can characterize hyperelastic material behavior through uniaxial tension test only .
The model in Abaqus/Explicit provides the option to specify a cutoff value for the maximum principal tensile stress that the material can sustain. The maximum principal stresses computed by the program will stay at or below this value. . When nonzero Poisson effects are defined, it is highly recommended that you provide uniaxial test data in .ABAQUS requires that cohesion creep properties be measured in a uniaxial compression test. Figure 4.4.4–6 Equivalent creep stress for cohesion creep. The equivalent creep stress, , is determined as the intersection of the equivalent creep .A simple uniaxial compression test is sufficient to define the evolution of the yield surface.

The kinematic hardening component is defined by specifying half-cycle test data, where the data . Raw load-displacement data from the uniaxial compression test are shown to be contaminated by both machine deflection and seating effects at the specimen surface. Machine displacement is found to be a nonlinear and reversible function of applied load, insensitive to the displacement or loading rate, but sensitive to environmental conditions such as temperature. .
The example demonstrated the self contact and use of hyper elastic material in Abaqus Standard. A series of experiments and numerical simulations based on uniaxial compression test have been carried out over the past decades to study the mechanical failures (Zhang and Wong, 2012; Liu et al., 2021; Fu et al., 2022).
