Abstract
Three different novel sandwich coupon designs comprising continuous unidirectional protective layers were directly compared with standard coupons to assess their potential to fully eliminate stress concentrations near the gripped regions. The gripping conditions were optimised using different grade sandpaper tabs at the end of the sandwich coupons. The sandwich type coupons yielded statistically significant increase in their average failure strain compared to that of the baseline tabbed coupons. However, the three sandwich coupon types did not show significant differences.
