000014252 520__ $$2eng$$aSteven test is an effective tool to study the relative sensitivity of various explosives. In this paper, we built the numerical simulation method based on the thermo-mechanical coupled material model to simulate the Steven test. In the model, the stress-strain relationship is described by dynamic plasticity model, the thermal effect induced by impact is depicted by isotropic thermal material model, the chemical reaction is described by Arrhenius reaction rate law, and the effects of heating and melting on mechanical properties and thermal properties of materials are also taken into account. The numerical model was validated by comparing the obtained deformation of the target of Steven test and the ignition threshold for explosive reaction with the experimental data in the references. The calculated results are in good agreements with the experimental data, which suggests that this method is capable of simulating Steven test.
