I am interested to understanding the correlation between theoretical prediction with experimental data of mechanical behavior of polymer blends. Further, studied various articles, and upon back calculating data most of the equations related to phase angle, solvent avidity (p) were obtained exact values from which now I can differentiate between continuous matrix and filler.

Whereas, while fitting Isostrain (Gx> Gy)

GC= Gx*phix+Gy*phi y----- eq1

Iso stress (if Gy> Gx)---- eq 2

1/GC=phix/Gx+phiy/Gy

For composite where filler particle much softer or much harder than surrounding then

Gc=Gx*phix-- eq 3

1/Gc=phix/Gx --- eq 4

While fitting eq 1 (when Gx> Gy) and eq 2 (Gy> Gx) it is giving some error values ranging from 0.05-0.8.

Further, I am fails to understanding the conditions for fitting eq 3 and eq 4

SO IT WILL BE VERY HELPFUL IF SOME ONE GUIDE ME ALONG WITH BACK CALCULATION OF THE DATA.

I WILL SHARE MY EXCEL FILE ON POLYMER BLEND
