DEFORMATION OF A CYLINDRICAL SHELL BY EXTERNAL PRESSURE

Abstract

The article considers the problem of determining the stress-strain state of a thin-walled cylindrical shell under the action of external pressure. Such structures are used in many machines, for example, aircraft casings, submarine casings, drums of hoisting machines. Equations were derived for circumferential, longitudinal and axial displacements depending on the geometric dimensions and elastic properties of the rope and drum. At the same time, the hypotheses about the non-tightness of the shell in the circumferential direction and the absence of displacement were not accepted. This brings the design scheme much closer to the actual operating conditions of the cylindrical shell.
