Dear Jorgen,

I received your approval to use Mcalibration for the purpose of my thesis, which I am very grateful for.
I did run into a little problem and hope you can help me to identify and solve it:

To calibrate an Ansys Monney-Rivlin 5 parameter material model I tried to use experimental data for 3 different load cases. However, Mcalibration only accepted the tensile test data. For the other two load cases I got the error message: "Simulation failed. No data available." Also the runtime output told me the final stress for the load cases 2 and 3 is 0.
Here is a screenshot of the situation (I hope that helps):

Here is some additional information that may help:

Load Case: Lancker Tensile Up to 0,3

Time: max=4.5e-05

Engineering strain: min=0, ave=0.117391, max=0.3

Engineering stress: min=0, ave=0.260989, max=0.4938

Young's modulus: 4.88 (average engineering modulus for the first 1% of strain.)

Engineering strain rate: min=5000, ave=6956.52, max=20000

Average engineering strain rate magnitude: 6956.52

Median engineering strain rate: 5000

 

Load Case: Lancker Biaxial(Compression) Up to 0,3

Time: max=0

Engineering strain: min=0, ave=0.15, max=0.3

Engineering stress: min=0, ave=0.401342, max=0.9058

Engineering strain rate: min=0, ave=0, max=0

Average engineering strain rate magnitude: 0

Median engineering strain rate: 0

 

Load Case: Lancker Shear Up to 0,3

Time: max=0

Engineering strain: min=0, ave=0.15, max=0.3

Engineering stress: min=0, ave=0.087851, max=0.1688

Engineering strain rate: min=0, ave=0, max=0

Average engineering strain rate magnitude: 0

Median engineering strain rate: 0

I was able to figure it out:
I did not have data for the time, bur only for the stress and strain.
Fabricating some values for the time did help me to solve my problem.

Good to hear that you were able to solve the problem.
