how to get Gc and Gt according to material parameters for masonry structures

[xgx]

Dear STKO team, I want to ask how I can get Gc and Gt according to the material parameters in the following pictures when I am modeling masonry structures. When I try to calculate Gc and Gt according to Professor Massimo's paper, I find there is no information for the stress-strain curve, so do I need a constitutive model for brick and a constitutive model for mortar? If you can answer my question, I'd appreciate it.

There are some formulas for concrete but not for masonry. You should calibrate them on experimental results
