Difference between maximum shear stress and absolute shear stress

What is the difference between maximum and absolute shear stress in multi axial stress system?

• would it be different if it was not multi axial? Sep 20 '17 at 6:15

absolute shear stress is probably the absolute value of the shear stress on a specified orientation which may or may not be the special orientation that gives the maximum. I say probably because the question hasn't given enough context, but I expect you are seeing something like abs(sxy) in a given coordinate system
