The modified split Hopkinson pressure bar experimental schematic.
(a) The stress analysis of the ethylene glycol; (b) The stress pulse of the ethylene glycol with a length of 95.4 mm under the peak incident stress 47.2 MPa; (c) The transmission pulse of ethylene glycol with a length 95.4 mm under the peak incident stresses of 36.5 MPa, 38.7 MPa, 44.4 MPa, and 47.2 MPa, respectively.
(a) Peak stress pulse of ethylene glycol on the modified SHPB; (b) Comparison the stress pulses under the peak incident pulse about 47 MPa for the ethylene glycol and the 62 vol/vol. % dense particle suspension; (c) The incident pulse energy ( E I-S ) and the transimision pulse energy ( E T-S ) for the ethylene glycol and the suspension; (d) Strain gage signals for two experiments performed under identical impact conditions. The R value is used to verify the contact ratio in two tests. The R value is below 15% in the range of the transmission plus, which indicates the two curves are in good coincidence.
Peak stress pulse of ethylene glycol unit:MPa.
