Dear Mr.Nga man li,

The material properties of anisotropic soils can be defined easily by defining the permeability of soil in both horizontal and vertical directions. Usually, permeability in the horizontal direction is more than in the vertical direction. Also, you define the elastic properties also for the soils. The varying modulus of soil can be define easily in ANSYS software. all the best in your research..

Hi Professor Karthigeyan,

I am looking at ceramic samples. Do you know if inputting stress strain curve in the anisotropic directions can be done in ANSYS workbench?

Thanks,
