| Abstract: | A mixed finite element method on the basis of the theory of contact elasticity is presented for calculating the distribution and the magnitude of the stresses in the laminate containing pin loaded holes. The analysis included the effect of pin elasticity, clearance between the pin and hole,and friction between the pin and the hole on the stresses around the hole. The results indicate that the friction and laminate ply orientation significantly affect the distribution and magnitude of the stresses. However,inclusion of pin elasticity reduces the stress concentration and increases the load capability slightly. |
