curve fitting and inverse calibration

Recommended Posts

Hi,

I am quite new to the hyperwork and hyperstudy.

I am going to do inverse calibration approach to find the hyperelastic material properties for our developed foam material.

It means that, I have force-displacement curve from experimental compression test and want to fit the curve with crushable foam model in ABAQUS software.

would you please let me know if there is any tutorial that can be helpful as I just installed Hyperwork licence (my organisation, UoA, provided it).

 

Thanks

Madie

Hi,

 

while not exactly foam material calibration, these tutorials might be helpful:

HS-1506_ Material Calibration with a Curve Difference Integral.pdf HS-4200_ Material Calibration Using System Identification.pdf

 

Side note: Radioss material law 69 supports Test Data Input to automatically fit hyperelastic coefficients.
