Abstract
A three-dimensional solution valid in a composite laminate with a rigid fastener hole is obtained by combining a singular asymptotic solution with the B-spline displacement approximation. The hybrid approximation developed for the open hole problems was extended to rigid fastener hole problems. A near singular term of the asymptotic expansion present in the filled hole problem only was taken into account in order to obtain convergent solution with coarse spline approximation mesh. A bearing loaded [45/-45]s laminate was considered, and the multiplicative factors of the singular stress terms at the hole edge and ply interface were obtained.
