Webb12 nov. 2024 · The analytical solution (Einstein and Schwartz 1979) is expressed using the notation in Figure 1. The support displacements consist of a radial, us, and a tangential, vs, component. The internal stresses consist of an axial thrust, T, and a bending moment, M. The interface contact stresses consist of a normal, σR, and a shear, τRθ, component.
