　　To improve prediction accuracy of transparencies bird-strike resistance,a concept of nominal-strain-rate was introduced in present paper.Then,combining the equation of material dynamic constitutive with bird-strike fitting responses,a modified bird-strike analysis model was inversed and proved to be highly accurate,with only 0.7%error compared with the typical bird-strike tests.
