Application of Quantification of Uncertainties Method in Detonation Simulation to Steven Test

摘要

Detonation sensitivity is important index for measuring initial capability high explosive. Steven impact test is one of the basic tests about gauging and has greatly increased the fundamental knowledge of practical predictions of impact safety hazards. We describe a modified form of Lee-Tarver reactive flow model, Lagrange model and elastoplasticity hydrodynamics model. It is better suited for test data. Numerical simulation has become more important in designing detonation systems and the quantification of its uncertainty is also necessary to reliability certification. We try to apply quantification of uncertainty in detonation simulation to Steven impact test for proof feasibility of the quantifying uncertainty framework in practical problem.
