Effect of Shape of External Pressure Impulse and Design Parameters of Thin Circular Cylindrical Shells on their Stability (Vliyanie Formy Impulsa Vneshnego Davleniya i Konstruktivnykh Parametrov Tonkikh ku Rgovykh Tsilindricheskikh Obolochek na ikh Ustoyichivost),
Abstract
The report studies the effect of the shape of an impulse of uniform external pressure of sufficient magnitude to cause a bend on the order of shell thickness in thin closed cylindrical shells. As a consequence of inertia in a shell during dynamic loading, the rate of application of the load will be greater than the rate of buildup of deflections. Therefore, the loss of stability takes place at a higher energy level and this leads to possible changes in the shape of wave formation. In order to account for this phenomenon, a shell at a certain level of stability is viewed as an elastic system with k degrees of freedom and the process of wave formation in it assumes a shape which is most favorable for a given load.
