    Tensile Test - Force Strain Rubber

    Michael Kuhn

      Hello fellow Simulators,


      im trying to verify a tensile test of a rubber like material.

      The material can handle strains up to 300% (last datapoint of the diagram).

      I am running a 2-Dimensinal non linear simulation.

      The Non-linear tensile test data (material data) looks like the following:

      Material DataGeometry

      I´m using the Nonlinear-Elastic Material model.

      Strains up to 243%

      Evaluation of the required Force:






      As shown in the force/time diagram the required force converges at a value of approx. 10 N.
      But looking at the material data the force should not converge - shouldn´t it slightly rise with higher strains? (taking into account that the area decreases)
