Inverse Engineering Force Estimation

Hi

I have a rubber hyperelastic material that I need to estimate the forces that cause its deformation when imaged on ultrasound images.

I know there is a way to do it in ANSYS, by applying an ogden 1st order model and import the stress-strain experimental data I got from testing the material using an Instron device. But I need to make the geometry take the deformation as it appears on ultrasound images. For this case, I need to import the deformation profile in ANSYS. The deformation profile I have it in excel data where X is the length of the material and Y its thickness as it appears on the image, for each column. How do I import the deformation profile from excel to ANSYS and make the geometry take the deformation and at the same time yield the force distribution.

If not using ANSYS at all. What other methods can I implement to get the force estimation out of the strain from images?

Looking forward to your precious advice.
