CONTACT STRESS DISTRIBUTION IN PIN LOADED ORTHOTROPIC PLATES

Abstract:
An analysis is presented for determining the stress distribution in pin loaded composite joints. In this analysis, it is assumed that the pin is rigid, clearance exists between pin and plate, and the coefficient of friction remains constant throughout the contact region. The analysis also assumes that the contact boundary at the pin-plate interface is unknown a priori and must be determined as part of the solution. The boundary conditions at the pin-plate interface are specified in terms of the unknown contact angle and a trigonometric series used to represent the displacement field in the contact zone. Numerical results are presented for stress distribution for  graphite/epoxy laminates. |
