Figure 6.

(Color online) Contours of (a) the transverse tangent Young's modulus of the cover layer $E_{x\_\mathrm{cover}}^t$, (b) the transverse tangent Young's modulus of the body layer $E_{x\_\text{body}}^t$, (c) the AP tangent Young's modulus of the cover layer $E_{y\_\text{cover}}^t$, (d) the APtangent Young's modulus of thebody layer $E_{y\_\text{body}}^t$, (e) the ratio $E_{y\_\text{cover}}^t$/$E_{x\_\text{cover}}^t$, and (f) the ratio $E_{y\_\text{body}}^t$/$E_{y\_\text{cover}}^t$. All data were from case 1.
