Abstract :
This article has been retracted: please see Elsevier Policy on Article Withdrawal (). This article has been retracted at the request of the editors and authors. The authors realised recently that the FE model used in the paper is different from that shown in Figure 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 Figure 9 indicates that the transition strain-rate predicted from the correct model has not been observed up to 104 1/s, which is two orders higher than the transition strain-rate predicted by the wrong model (in the order of 102 1/s). Since the strain-rate of 104 1/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 102 1/s, which completely undermines the conclusion of the study. The authors apologise for misleading any readers due to this unfortunate mistake.
