The numerical analysis of the propagation of stress waves and the allied scabbing phenomena in a steel plate under explosive attack is made, by using a model of one-dimensional flow The results are compared with our experimental results which were carried out several years ago. It is found out that, in case the elastic-ideally plastic model for steel plate and the cumulative damage spall criterion are used, the calculated thickness of the major spall is in reasonable agreement with that observed in the experiments. An approximate formula for the thickness of the major spall is presented and the "mica-splitting" phenomenon about the minor spalls observed in the experiments is satisfactorily explained.

The entropic increase of a plate drived by explosive has been researched in one dimension system. Usually. The high explosive is contact with a plate immediately. There is the increase entropy of in the plate resulting from the interaction of a detonation with the plate, while increasing its kinetic energy.The rather idealized problem of detonation products initially at CJ state that expands in one dimension into a void and then accelerates a plate has been analyzed in mathmatical detail. It is believed that the technique described in this report can decrease the enlropic increase and increase some kinetic energy of the plate by choosing the proper length of void and thickness of the plate.

A simple Lagrangian analysis method to give the reaction flow field in detonation reaction zone of high explosives is proposed in this paper.With knowing the equations of state of the unreacted explosive and the reaction products,as well as with some appropriate assumptions,we could obtaine the relationship of p(λ) and u(λ) ,etc across the detonation reaction zone without specifying the reaction rate function(where, p is the pressure, u is the particle velocity, λ is the reaction progress variable).According to these relations and the experimental results about p(λ) (or u(λ) )across the detonation reaction zone,the reaction flow field across the detonation reaction zone could be obtained by means of interpolation or data fit.We used the methed mentioned above to get the reaction flow field across the reaction zone of PBX 9404.

给出了一种简单的、对高能炸药爆轰反应区流场进行拉格朗日分析的方法。若已知未反应炸药和反应产物的状态方程,采用适当假设,我们可以在不知道反应速率函数的情况下得到爆轰反应区中的关系p(λ)和u(λ)等。根据这些关系及爆轰反应区中拉氏量计的实验结果p(t)[或u(t)],通过插值或数据拟合可以得到爆轰反应区中的反应流场。我们将此方法应用于PBX-9404炸药,并得到其爆轰反应区中的反应流场
