DEFLECTIONS AND STRESSES IN HEMISPHERICAL LIGHTWEIGHT CELLULAR SUPPORT STRUCTURE WITH FLEXIBLE SUPPORTING SHELL

PDF Version Also Available for Download.

Description

A spherical component is frequently supported by a hemispherical lightweight cellular core which is in turn supported by a flexible elastic support shell. Design information is given on computing the normal and shear stresses in the core as well as circumferential and meridional stresses in the flexible support shell. A set of graphs is given showing the ratio of these stresses for the case of a flexible support shell to the corresponding maximum stress for the case of a rigid support shell, plotted against the meridional angular coordinate of the hemisphere. Two dimensionless geometrical and material parameters appear as variables ... continued below

Description

A spherical component is frequently supported by a hemispherical lightweight cellular core which is in turn supported by a flexible elastic support shell. Design information is given on computing the normal and shear stresses in the core as well as circumferential and meridional stresses in the flexible support shell. A set of graphs is given showing the ratio of these stresses for the case of a flexible support shell to the corresponding maximum stress for the case of a rigid support shell, plotted against the meridional angular coordinate of the hemisphere. Two dimensionless geometrical and material parameters appear as variables in these graphs. A second set of graphs to be used for obtaining displacements of the flexible shell with respect to the supported sphere are also plotted in this manner. For computing the maximum stresses in the shell or core, a graph is given showing the maximum value of the stress ratio plotted against a dimensionless material-geometrical parameter. (auth)
