The purpose of the work is the development of joint research activities in the field of vibroacoustic anisotropic metamaterials Fraunhofer LBF (Germany) and NTU "KPI". Formulation of numerical modeling problems of metamaterials for determination of their characteristics. Development of vibroacoustic metamaterials as a new measure for vibration reduction. Development and research of measures of passive and active vibration reduction. Research Methods - Finite element method for deformation calculation of constructions caused by static and impulse loads, numerical method for calculating the mechanical characteristics of composites, structural optimization methods. The method of numerical calculation of the elastic characteristics of a composite is developed. This avoids the costly physical experiments of composites deformation. A software product for the automated calculation of the elastic characteristics of a composite in the APDL language for the ANSYS software complex was created. The deformation of cushioning pads under pulse loading is investigated.
