Taking the split Hopkinson pressure bar(SHPB) test data as training samples
an implicit dynamic constitutive model of steel fiber reinforced concrete(SFRC) was proposed with the improved BP neural network program. On the basis of ABAQUS/Explicit
a userdefined material subroutine VUMAT was compiled with FORTRAN language
embedding with the neural network constitutive model into finite element calculation. With SFRC structure's response under impact load as case study
it is shown that the constructed constitutive model and its finite element method are effective.
