Solving non -custody of the theory of sustainability

The contents of the textbook complies with the program of training specialists in the directions Dynamics and strength of Masha, Applied mechanics and related disciplines. The basics of the theory of stability of elastic systems are presented, features and methods for studying the stability of mechanical systems that are in non-conservative loading are analyzed. Numerous elastic systems under the action of potential and non-consistent loads are considered. The focus is on the construction of the boundaries of sustainability areas in the parameter space. For a number of nonlinear systems, a study of crate behavior was conducted. In addition to the traditional methods of sustainability research, the rationale is given and the construction of an indignant movement equations by the end element method. Solved a large number of tasks with the illustration of the results obtained by extensive graphic material. The book is intended to students learning the disciplines Material Resistance, Stability of Mechanical Systems, Dynamics of Machines, and can also be useful engineers engaged in designing and calculating objects of modern technology.
