Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2  Improvement and verification of calculated models and algorithmic software for the analysis of static and dynamic characteristics of composite structures with nano-reinforcement in the framework of two- and three-dimensional models is carried out. Algorithmic software for analysis of composite response to impulse and shock loads has been modified. The calculated model of deformation of adapters from composite functional-gradient materials under the action of operational impulse loads is developed. A computational-theoretical approach to study of layered thin-walled structure dynamics has been developed. Methodological software for calculations of nonstationary oscillations, the implementation of which involves using of the method of modeling damages in the form of delamination and formulating the conditions of local loss of stability of the layers of composite structure is modified. The dynamic reaction in the fairing separation system during its operation is investigated and the influence of the loss of stability in the stratification of the composite element on the quantitative and qualitative indicators of oscillations is estimated.
