| Abstract: | The distribution characteristics of stress field of linear charge explosion were studied by means of the dynamic photoelasticity models experi-ment.The experimental results showed that the priming mode and position effect on the distribution form of stress field generated by linear charge explosion. The dynamic, photoelastical stripes of instantaneous explosion stress fieid of linear charge were successively recorded for the first time,and the ideal distribution form of stress field was obtained. |
