There were developed: a new technique of construction of borders of elastic systems' dynamic stability areas under stochastic stationary and periodic nonstationary parametric excitation; an effective technique of numerical investigation of processes of geometrically nonlinear deformation, stability and supercritical behavior of thin inhomogeneous shells at an operation of static temperature and force loads; a methodology and structured system of a research of the high-speed deformation process of shells' constructions under impulse high-power actions, which have based on application of a principle time-temporarily decomposition; an effective technique of numerical investigation of stress-strain evolution and cracking process of ferro-concrete designs in three-dimensional statement and technique of definition of a rated life-time of spatial bodies under creep loading condition with the account of damage accumulation process on the basis semianalytic finite element method. On the basis of the developed techniques decisions of series of practical problems were obtained. Product Description popup.authors popup.nrat_date 2020-04-02 Close
