Abstract

In this paper, the contact stress between two different finite hollow cylinders connected by a bolted joint is studied. The three dimensional theory of elasticity is used to analyse the contact stress and the deformation in laminated finite hollow cylinders whose both sides are compressed axisymmetrically under a local uniform pressure. By neglecting shearing stress on the contact surface, an exact solution satisfying the remaining boundary conditions is obtained. Numerical calculations are carried out for various rigidities and thicknesses of the finite hollow cylinders under various loading conditions. In order to examine the results of the theoretical analysis, the contact stress is measured experimentally by using pressure-sensitive pins attached to a finite hollow cylinder. It is confirmed that the theoretical results agree well with the experimental ones except at the vicinity of the loaded area.
