The method of research of elastic systems dynamical stability under few stochastic parametric loads such as white noise, exponentially correlated load and load, which consist of determinate periodical and stochastic parts, were developed. The stability problem about moment functions was considered. The dynamical stability of some objects were analyzed with application of this method. The algorithm of stress analysis, stability and supercritical behavior of heterogeneous shells under temperature and force loads were developed.The computational modeling method of force and heterogeneous temperature loads simultaneous acting was developed. The technique of self-correcting characteristic of stability task solution algorithm was built. Thecomputational modeling of dynamic process geometric nonlinear shell deformation under large-scale, impulse load which based on mathematical model of 3-D finite element end Newmark integration method was fullfiled. The effective approach for resolve 3-D problem of periodic and forced oscillations of heterogeneous solids of revolution and prismatic solids of irregular shape and structure was worked out with use of semianalytic finite-element method. New types of finite elements for dynamic problem was developed. New solutions of 3-D dynamic problems for real complex object were obtained.
