Experimental Study on Constitutive Relation of one RDX-based Aluminized Explosive

摘要：

　　Mechanical behaviors of one RDX-based aluminized explosive were investigated experimentally by split Hopkinson pressure bars(SHPB)at different strain rates(ranged from 840 to 1650 s-1)respectively.Nonlinear stress-strain curves at different strain rates were obtained.The results show that mechanical behaviors of the RDX-based aluminized explosive are obviously rate-dependent,the failure stress increases as the increase of strain rate,but failure strain keep invariant.The constitutive model of modified Z-W-T nonlinear visco-elastic was fitted by using the tress-train curves,which is in accord with the experiment curves well.
