The paper studies the effect of the amount and distribution pattern of nanoinclusions in a high-strength mesocomposite matrix on its plastic deformation under dynamic loading. The study is performed on mesocomposite specimens shaped as hollow thick-walled cylinders subjected to combined shear/compression loading with an explosive. It is found that homogeneous strain decreases with the growing volume fraction of nanoinclusions. The mechanical texture formed by the distribution of nanoinclusions in mesocomposite bars is shown to influence the deformation and cracking mechanisms. Additionally, the influence of structure is studied by computer simulation. The simulation has revealed that plastic deformation is rotational in the mesocomposite with chaotic structural distribution.
