Dear all,

I would like to determine a principal stress direction though the thickness of a pressure vessel.

The pressure vessel is modelled with a 1°order brick element and constrained with axisymmetric constraints.

After the analysis I obtain this plot:

I need to extrapolate the principal stress direction in nodes along the thickness in the major stressed area.

I use arrow contour style but principal stress are oriented along the Global coordinate system (the reference coordinate system in the various figures).

I then insered a local coordinate system, oriented with 1 of the axis though the thickness.

And then I selected the new coordinate system:

THE PROBLEM IS:

After the definition of new coordinate system, the vector are aligned to these vector, BUT THE VALUE ARE THE SAME.

I neew to extrapolate (plotting and list in data table, the 6 stress tensor component, to using them in other software.

Can anyone help me?

I attach modfem ad .FNO results.

Best regards

Stefano
