Load‐Transfer Problems for Transversely Isotropic Elastic Media
Publication: Journal of Engineering Mechanics
Volume 116, Issue 12
Abstract
This paper presents a unified solution procedure to analyze the load transfer from a partially embedded long (finite) cylindrical elastic bar into a transversely isotropic elastic half‐space. The bar may be subjected to a torque, an axial force, a horizontal force, or a bending moment at the top end. The solution approach is different from that proposed by Muki and Sternberg (1970). It is based on the interaction between a one‐dimensional elastic bar and a three‐dimensional elastic half‐space with a cylindrical cavity. The displacement compatibility is achieved along the contact surface between the bar and the half‐space. A variational technique coupled with a boundary integral equation scheme based on a set of exact Green's functions is used in the analysis. The boundary conditions at the top end of the bar are incorporated into the variational formulation through a set of Lagrange multipliers. Selected numerical results are presented for elastic bars embedded in some representative transversely isotropic media.
