An account of plastic deformations under beam vibrations

The article proposes a method of dynamic design of damaged constructions with an account of plastic strain. The permissive equations are based on the theory of discrete systems time analysis. The paper considers the hysteretic nature of elastoplastic systems work. As a result of multicycle deformations an account of strain accumulation is carried out. The destruction of the supporting member takes place when the total plastic strain exceeds the limit value. The author considers the method by the example of vibrations of rigidly clamped beam, in which through the dynamic loading angle brace breaks up.
