Anisotropic closure model in mixed cells. The paper offers a new anisotropic closure model for equations of Lagrangian gas dynamics and elastoplastic in mixed cells containing several components (materials). The model is realized in code EGAK, numerical research of a method on test problems is conducted. The paper presents full statements of two one-dimensional and one two-dimensional problems, and also the description of processing technique for results. The numerical results are compared to results obtained by another closure model which is available in code EGAK, and analytical decisions. The analysis and discussion of calculations results are presented.
