Dear Support ,

I am the user of Caesar II 5.2 in which ISO 14692 is included.

As per ISO 14692 we have to compare the axial vs hoop stress by stress envelope for Pipe, Elbows and Tees.

Please expalin the below terminology as it is not shown as per ISO 14692.

Sal(1:1) - Long term Axial stress at 1:1 stress ratio
Shl(1:1) - Long term Hoop stress at 1:1 stress ratio
Sal(2:1) - Long term Axial stress at 2:1 stress ratio
Shl(2:1) - Long term Hoop stress at 2:1 stress ratio

Please advice the basis of ISO 14692 calculation in Caesar II without above input.

If you don't know what is mentioned here, please first study GRP pipe stress analysis and GRP pipe mechanical properties and behaviour in general !

The values you mention here are specific points on the stress envelope. The point where hoop and axial stress are the same (1:1) and the point where hoop = 2x axial (2:1).

You can't do a ISO 14692 stress analysis if you don't have this information.
