Hi, I have compression strain, lateral strain, and compression stress data. I see that the Ogden HyperFoam model creates a beautiful fit to the compression stress-strain data. Now, I'd like to see if it attempted to fit the lateral strain. If, by default, it doesn't, how to invoke? Is it even necessary to fit the lateral strain? Are there any videos or blogs on the subject?

Sorry, I didn't mean to offend: by "it", I meant the MCalibration software.
That is a good question. By default, MCalibration only tries to match the experimental stress-strain response. But if you have transverse strain data, then you can instruct MCalibration to also use/fit that data during the calibration. To do this all you need to do is to specify a fitness weight for the transverse strain for the desired load cases. By default the fitness weight for the transverse strain is set to 0. Here's an image.
Thank you for response. That helps.
