In advanced engineering fields such as aerospace engineering, composites are finding increasing applications because of their high strength/weight ratios. Pin joints are unavoidable in complex structures. With splice joints in spars, bulkheads etc., multiple pin/rivet connections are used. Accurate analyses of stresses around pins in such situations will assist the designer to a great extent. The pins are metallic and are generally stiffer than the composites. For the purpose of analysis, the composite plate is treated as an orthotropic laminate and the pin as a rigid circular disc, and a two-dimensional linear elasticity theory is used. The geometry considered is that of a rectangular plate with a single circular pin on one of the middle lines subjected to different loads uniformly distributed stresses on two opposite sides. This is representative of a pin under the classical bearing bypass loading. In this paper an analysis of this configuration accounding for the proper pin/plate interface conditions is developed. The results highlight the nonlinear behavior of such a joint with load magnitude(s). A quadratic stress criterion is applied to evaluate the critical loadings and the corresponding strength envelopes are generated. The effect of interference fit parameter on these envelopes is estimated.
