Abstract

Theaxialstressandtheaxialdeformationofthechargeexplosiveinaprojectilewastheoreticallyanalyzedduringthepenetrationprocess. Thecorrespondingdistributionfunctionsalongtheaxis ofthechargeexplosivewereattainedbyconsideringtheelasticandplasticdeformationofthecharge explosive.Basedonthefriction-inducedheataswellastheheatconduction,thetemperaturedistributionalongtheaxisofthechargeexplosivewasobtained.
