摘要

The authors realised recently that the FE model used in the paper is different from that shown in Fig. 4 of the paper. The calculations were mistakenly undertaken using an axisymmetric FE model of a tube for the solid SHPB specimen. The authors examined the possible consequences of this mistake. The recalculation of Fig. 9 indicates that the transition strain-rate predicted from the correct model has not been observed up to 10~4 1/s, which is two orders higher than the transition strain-rate pre dicted by the wrong model (in the order of 10~21 /s). Since the strain-rate of 10~41 /s is already outside the testing range of conventional SHPB set-ups, the authors can no longer draw the conclusion that there is considerable lateral confinement contribution to the testing data from conventional SHPB tests on polymers when the strain-rate is greater than 10~21 /s, which completely undermines the conclusion of the study. The authors apologise for misleading any readers due to this unfortunate mistake.
