Nonlinear elastic materials

I plan to perform analyses for 'nonlinear elastic materials' (that are not rubber and/or elastomer) by using Autodesk Simulation 2013.
How to analyze nonlinear elastic materials by using stress-strain curves and Poisson's ration in MES analysis?  Is it possible for such analysis?

 

Best regards,

Akihiro Matsuda

Hi Akihiro,

 

Yes, you can do with Autodesk Simulation Mechanical 2013. 

 

If you have strain/stress curve of your elastic material, you can use curve-fitting function of hyperelastic or hyperfoam materials. This will estimate the coefficients of strain energy density function according to hyperelastic material model you choose. 

 

If you just have Young's Modulus and Poisson's ratio, then Neohooken is the good starting point to try. 

 

Good Luck!

Hi Jaesung,

 

Thanks quick reply!  I found some other FEM softwares that have 'nonlinear elastic model'.  These software's 'nonlinear elastic model' use both 'Stress-Strain curve' and poisson's ratio, without using strain energy density functions.
Anyway, I will try to solve my problem by using your recommendation scheme.

 

Thanks again!
Akihiro.
