I have considered modeling a simple cylindrical piece of wood in tension. I think that the definition of the material should be using ENGINEERING CONSTANTS, indicating different coefficients according to the longitudinal and radial directions, according to:
first line: E1,E2,E3,v12,v13,v23,G12,G13,
second line: G23,T
I understand that it could be like this:
*Solid section, Elset=timber, Material=oak
These lines have been entered with the “Edit CalculiX Keywords” option.
Could someone tell me how I can ensure that the 1,2,3 directions with which the constants are defined correspond in the finite elements to the global Z,X,Y directions of the model?
Thank you very much in advance for your attention.
