Dear Bill,

 

Thank you for your help. This makes a lot of sense. 

NSEL command for the stress only accepts the following components:

X, Y, Z, XY, YZ, XZ  ---> Component stress.

1, 2, 3 ---> Principal stress

Eqv ---> Equivalent stress

 

Would you please tell me how we can get the principal stress values (Sx in your figure) if our line elements are oriented in different directions (not necessarily in the X direction).

 

Thank  you
