ATTENUATION OF STRESSES FOR BURIED CYLINDERS

An analysis is presented for the interaction of an elastic cylindrical shell embedded in an elastic medium which is loaded by a surface overpressure. Non-dimensionalized equations are presented for the interaction loads between the shell and the medium; for the thrusts, moments, and displacements in the shell; and for the stresses and displacements throughout the medium. The manner in which the circumferential extensional stiffness of the shell, the circumferential bending stiffness of the shell, and the shear load transfer between the shell and the medium influence the interaction problem is clearly indicated. The analysis is made through the use of extensional shell theory for the shell and Michell's formulation of Airy's stress function for the meduim. The equations for the medium reduce to the free cavity case if the shell stiffnessess become zero, and reduce to the rigid inclusion case if the shell stiffnesses become infinite. /Author/
