Product: Abaqus/Standard Abaqus/Explicit
In each input file a single element is subjected to a uniaxial load. The input files consist of two steps. In the first step the load is gradually increased until it reaches the prescribed value. In the second step the value of the load is kept constant for a specified time. These tests verify the correctness of the creep behavior with different element types.
Material:
The nonlinear viscoelastic material consists of three or four networks, including a purely elastic network. The strain-hardening power law, the hyperbolic-sine, and the Bergstrom-Boyce creep models are used to model the viscoelastic behavior. Creep model coefficients are shown in Table 2.2.8–1, Table 2.2.8–2 and Table 2.2.8–3. Several different hyperelastic materials are tested, as described in Table 2.2.8–4.
