In the book on MSG and our code SwiftComp, we used the common Voigt notation 11, 22, 33, 23, 13, 12 to arrange the stress components into a column matrix. I know that Abaqus, Ansys, and Nastran might use different notations, can you tell me what are the conventions each one used?
Adding to the answer from Xin Liu Abaqus does use the aforementioned 11, 22, 33, 12, 13, 23 component order with a distinction of internal handling in Abaqus/Explicit. There, the components are stored in different order 11, 22, 33, 12, 23, 13 which is important when programming user subroutines (ie VUMAT).

As far as I know, the notation arranges as 11, 22, 33, 12, 13, 23 in Abaqus, and 11, 22, 33, 12, 23, 13 in Nastran.

In ANSYS, it is 11, 22, 33, 12, 23, 13, and it is the same as Nastran.

I can conform Erazem's comment. VUMAT uses a different order (11, 22, 33, 12, 23, 31) from say, UMAT (11, 22, 33, 12, 13, 23).
