Contact Stresses between Two Cylindrical Bodies: Cylinder and Cylindrical Cavity with Parallel Axes – Part I: Theory and FEA 3D Modeling

This paper presents the results of a study carried out using the Finite Element Method, on the contact stresses between two bodies: cylindrical body in a cylindrical cavity. The results are compared, following the analysis, to the results calculated on basis of the relations in H. Hertz's theory. The analyzed situation is: cylindrical body of radius R1 in a cylindrical cavity of radius R2, both bodies having parallel axes.
