Material Properties - Diffrent sigma Values for Wood

Maybe this Question is allready answerd but I wasn't able to find it out. 

I had a look in the Karamba materialpProperties CSV. file and recognized that the Material Wood is defined with 3 diffrent sig-Values for comp, bend and tention. 

Does that mean the FE-algorithem is able to work with a material like this ... so I would be able to create an other more or less orthotrop material in the csv.file ? 

Thank you for your help :)
