Bending stiffness of a material.

Tabitha Dujardin May 29, 2018 7:52 AM

Is there a possibility to give in the bending stiffness of a material in sollidworks?

I need to simulate a cord. But I would like to do this by drawing a wire with the same cross section as the cord and addapt the bending stiffness of this wire ( so it behaves like a cord).

Hi Tabitha,
You will find that when you start getting into materials that are soft enough that they can be deformed by your bare hands that SOLIDWORKS Simulation tends to have a tough time with the stability of the analysis. The only stable setup you might get going is a cable in tension. So, what is the situation you are trying to analyze and do you have a model/study setup with what you are trying to make happen?

  Ryan,
  
  I need to simulate the behaviour of multiple cords that are in a rubber. there comes a force on this rubber. I can do the simulation but I do not have good results as the bending stifness of the 'cords' is to high.

    The solver works because your bodies have a minimum stiffness. You can try decreasing the Elastic Modulus in the material applied to these bodies and see what happens but I believe the analysis will become unstable/unsolvable before you get to the point where you can have good results.
