Abstract

The paper shows a possibility of including a frequency-independent viscoelastic design resistance in calculation models representing composite structures with distributed parameters. Diff erential equations of the system motion include parameters of complex rigidity. The research puts forward a solution which helps solve stationary and non-stationary dynamic problems taking internal friction into account. This solution is found by using the calculation algorithm for prismatic shells involving the use of topological matrices. In the process of separation of variables, this approach yields a diff erential equation of linear oscillator motion with frequency-independent viscoelastic resistance.
