Podgorny Institute of Mechanical Engineering Problems of the National Academy of Sciences of Ukraine popup.description2  A model of non-stationary deformation of a typical structure of a solid propellant engine body made of functionally graduated composite materials in operating modes of loading at rocket launch has been developed. A method of dynamic analysis of composite rocket structures with arbitrary orientation of the anisotropy axes and аccounting of delamination has been developed. Within the framework of the three-dimensional linear theory of elasticity, an analytical-numerical method for studying the stress-strain state of cylindrical panels made of composite materials with an arbitrary type of nanoreinforcement across thickness under dynamic force loads has been developed Product Description popup.authors popup.nrat_date 2020-12-28 Close
