Is the formula for combining axial stress and 2 x shear stress through Mohr circle nominal stress as shown below is acceptable to combine stresses.

Depends. You have copied an equation, but you have given us NO information about what you are trying to calculate with that equation.

Try Von-mises or tresca criteria.

 

[MacGruber22]

daranguiz - those stress models are not appropriate for many many materials. The OP provided no information to suggest that they would be OK to use. What do you think could happen if he or she used VM or Tresca for some sort of concrete or structural glass design? Think and then think again before you post.

hsemus- another thing is that in a lot of applications, allowable stress is specified by some code, and that same code says or implies how that stress is to be calculated as well.
