Hyperelasticity - Extract Ogden fit coefficients from stress-strain

Is there an Altair product for evaluating stress-strain data and extracting the Ogden fit coefficients for subsequent use in a non-linear analysis?

I have attached the abaqus equivalent.

Thanks in advance

OptiStruct has the exact same capability embed on it

Take a look at the attached solver deck example.

Hi Adriano,

perfect..... many thanks!

Hi,

I'd highly recommend looking at our Compose solution as well which can export the necessary material cards for a given solver based on material test data. Pictured below is the Compose GUI toolbox, and I've attached a PPT.pdf of a summary.

Compose is available with HyperWorks Units.

Hi Joshua,

Many thanks for this document. Does this software have a database of standard hyperelastic/foam materials?

Thanks in advance
