Figure 234.1 Rubber Block Model Material Properties τ1 = 0.40 sec τ2 = 0.40 sec β 1 = β2 = 1 Geometric Properties L = 0.1 m Loading A = 0.01 Analysis Assumptions and Modeling Notes The analysis was performed using a single SOLID185 element. The rubber was simulated with an Ogden material model. The load was applied using a looping application of the displacement boundary condition. The plot displays the Cauchy stress evolution over the specified time periods. The accumulated stress relaxes after the load is removed at t = 16 seconds. The accumulated stress at t = 16 seconds and the relaxed stress state at t = 20 seconds are the verified results for this test. ANSYS Verification Manual .
