An analytical solution is presented for determining the stress distribution in pin loaded composite joints using Lekhnitskii’s complex stress function approach. In this analysis, it is assumed that the pin is rigid, no clearance exists between pin and plate, and Coulomb friction is assumed to act throughout the contact region. The analysis also assumes that the contact boundary at the pin-plate interface spans through half of the hole boundary. The boundary conditions at the pin-plate interface are specified in terms of the trigonometric series used to represent the displacement field in the contact zone. Numerical results are presented for stress distribution in (±45°)s and (04°/±45°)s carbon fibers reinforced laminates.
