STRESS-ANALYSIS FOR AN ELASTIC HALF SPACE CONTAINING AN AXIALLY-LOADED RIGID CYLINDRICAL ROD

The axially symmetric elastostatic problem of a half space containing a partially embedded, axially-loaded, rigid cylindrical rod is investigated. The rod is assumed to be in bonded contact with the half space and the half space surface is perpendicular to its axis. The problem is formulated by means of Hankel integral transforms and reduced to systems of coupled singular integral equations, where the unknown quantities are the normal and the shear stresses acting on the entire surface of the rod. Numerical solutions are obtained for several values of the aspect ratio, i.e. of radius to length, and for sufficiently small values of this ratio the results appear to be comparable to those of Muki and Sternberg for an axially-loaded rod. Comparison is also made for the percentage of the vertical resultant load carried by the base of rod with the results obtained by Poulos and Davis for a single axially-loaded incompressible pile. © 1979.
