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:
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)
