Figure 4
Two-dimensional WAXS characterization of NR material under combined tension and shear loadings. Figures in the left-hand column (a) describe experiment A where the sample is first stretched to 400% then sheared to 150%. Those in the right-hand column (b) refer to experiment B where the sample is stretched to 200% then sheared to 150%. (a1) WAXS pattern after 400% stretch showing crystallization. (a2) WAXS pattern after 400% stretch and 100% shear. (a3) WAXS pattern after 400% stretch and 150% shear. (b1) WAXS pattern after 200% stretch (no crystallization). (b2) WAXS pattern after 200% stretch and 130% shear. (b3) WAXS pattern after 200% stretch, 150% shear + 5 min relax. |
