Mathematical modeling of shock loading of the meniscus liner

Mathematical modeling of the high-velocity element formation process based on finite element method is presented. The proposed approach enables considering geometrical imperfections of the explosive device. The article contains general description of the proposed mathematical model including corresponding numerical algorithms. Selection of the suitable finite element formation is performed. Practical application of the proposed method is illustrated on the example of analysis of the imperfection influence on the kinematical and geometrical parameters of the elements.
