SUPPORTING POWER OF SKELETON AND CORRUGATED CIRCULAR CYLINDRICAL SHELLS DURING COMPRESSION,
Abstract
A method is proposed for calculating the supporting power of frames and corrugated circular cylindrical shells during compression. This method is based on the assumption that the longitudinal elements of the real shell, having initial bucklings, are in state of longitudinaltransverse buckling. Derived are calculation dependences individually for axially symmetrical and non axially symmetrical deformations. Resolving square equations graphically show the effect of individual parameters of the system on the magnitude of the destructive compression stresses. In the order of illustrations are given the examples of calculating the supporting power of corrugated circular cylindrical shells. Measures, leading to an increase in critical stresses of the shell and destructive stresses of individual corrugations or stringers, assist in increasing the supporting power of the system. The described method of calculating the supporting power can be applied to the case of transverse load, which, like buckling is capable of sharply reducing the supporting power of the shell. The relatively simple method of calculating the supporting power of framed and corrugated shells upon compression offers the possibility of making selection of system parameters from minimum weight conditions, and also to establish maximum buckling amplitude values, which may be committed at manufacture.
