Piezoelectric Material Properties, Compliance Matrix, Coupling Matrix and Relative Permittivity Matrix

Please login with a confirmed email address before reporting spam

I am trying to verify my model with BaTiO3 real data from the research papers.

We have values of piezo module , dielectric permeability , tangent of dielectric losses , the resistance and the capacity from experiments. But in COMSOL the piezoelectric material properties are in Matrix Voigt notation form. How can I used these values and convert them to Compliance Matrix, Coupling Matrix and Relative Permittivity Matrix . The Screenshot is attached. Thank you.
