(Occhipinti) Configuration of CNTs in the polymer composite under strain by stretching. (a) Graphical representation of curved CNTs with a set of segmented lines, (b) definition of angles for each directional vector of segmented line. (c) Calculation domain without strain. Red lines indicate the CNTs in the percolation network. (d) Calculation domain with strain. Curved CNT (e) of initial configuration and (f) after the strain is given to the composite box.
