The fixed point method consists to find the solution of F(X)=X.

One can not get fixed with the convergence condition |F'(X)|<1 because if the function has an optimum then |F'(X)|=0 even if the solution is not yet reached.

We introduce an efficient convergence test with the condition:

|Xn+1 - Xn| ≤ epsilon1 And |F(Xn+1)-Xn+1| ≤ epsilon2

The concrete stress-strain curve corresponds to the compression case with negative values plotted on positive axis. If one needs to plot the tensile curve for this concrete material this will be almost similar with {0.1*compression} stresses with positive values. Furthermore if one needs to plot on the same axis the tensile steel and concrete stresses for a composite mixture he needs to consider this last case. Fortunately the tensile and compression steel stresses are quite similar with opposite values.
