In PBT/SEBS/SEBS-g-MA systems, also the stress-strain plots were quite similar, although due to a degree of compatibilization, the stress concentration is decreased, which led to a marginal increase in the yield stress and quite a substantial enhancement of elongation (Fig.

A gradual taper allows for a smooth transition of load distribution from the edge to the center so as to minimize the possibility for a stress concentration from the sample edge and to focus the failure in the gauge section of the sample (Kretschmann 2008).
