Tensile Test - Force Strain Rubber

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)
