Hi all!

do you know how to output from CAESAR the
Sh=Hoop stress
Sa=Axial stress
Sq=shear stress or To=torsional stress
the latter is in the classic stress report with bending stress, I wonder if I can obtain the three components in the same report/or export file.

Or is there a way to output directly the maximum principal stress ?
many thanks

VERY SIMPLE.

You only need to check the 132 column reports in STRESS which tells you the full story.You get output for hoop and torsional shear besides the common stress outputs.

Few things you should remember:

1) The axial stress output does not include the axial stress due to restraint to free thermal expansion.

2) CAESAR II does not compute the shear stress due to variable bending moment as this value is zero at the outer fibre where the bending stress is max. Also where this stress is max( the neutral axis) the bending stress is zero.


CAESAR II gives output considering the principal stress concept in the form of max. 3D stress intensity. Stress intensity is defined as two times the difference of max. and min principal stresses.

This is the Tresca's approach.

If you don't want to use the stress intensity approach ,you can go in for the Von Mises approach ( distortion energy at yield in simple tension test) .Both approaches are available in CAESAR II. You only need to make change in confuguration set up.
