Sum of ply failure index in composite modeling

Hi to everyone.

I'm having some troubles to understand how to obtain a pure sum of two different load cases: i'd like to obtain the visualization of the sum of the ply and bond failure index, that are scalar values.

I've already tried to use derived results and derived load steps, but I still do not obtain the rigth results as aspected from a simple scalar addition

for example

load case 1 : max ply failure =0.12

load case 2 : max ply failure =0.16

what I'd like to display considering scalar is

max ply failure =0.28

 

thank you.

Giovanni

    the right procedure to obtain the scalar addition is

     

    derived results

     

    problem solved.
