Hi Mahawat,
could you share with us the curves to get an idea about the differences you mention?

MCalibration can import and work with equibiaxial data. We are working on adding support for non-equibiaxial data.

Hi Jorgen,
Do you have an update on the support for importing non-equibiaxial data?

Unfortunately we have not yet implemented that load case type. We are still interested in it, but we have a long list of things to work on, and that task has so far only a low priority. Can you give me one or more examples of why you need that ability? That would help me increase the priority of that task.

Many biological tissues, especially those in the cardiovascular system like arteries and heart valves, have been shown to experience non-equivalent bidirectional strains in vivo. When we have developed constitutive models for heart valve tissue in the past using MCalibration, we have only been able to use equi-biaxial data to generate the coefficients for the constitutive model. We’ve then had to validate multiple solutions by simulating nonequi-bixial loading in ANSYS and compare those results with our experimental testing. There is obvious error here without the ability to include nonequi-biaxial data into MCalibration and generate a constitutive model that reflects the complete behavior of heart valve tissue as it would in vivo.
