Spline approximation approach has been extended for three-dimensional stress analysis in composite laminates with elastic fastener holes. Contact problem describing the interaction between laminated composite and an elastic bolt has been solved by using variational approach and Lagrangian multiplier method. Rigorous criterion for definition of the contact zone size is derived from variational principle. Representative problems such as: bearing loading with zero and 4% clearance rigid bolt and filled hole tension problems were solved for homogeneous plates.
