Abstract

Interlaminar stresses near free edges in composite laminates have been analyzed considering interface modeling. Using the principle of complementary virtual work, the stresses satisfying the traction free conditions not only at the free edges, but also at the top and bottom surfaces of laminates are obtained. The interface modeling provides not singular stresses but concentrated finite interlaminar stresses. The significant amount of reductions of stresses at the free edge are observed compared to the results without interface modeling. The stress and strength analysis were performed and the results demonstrate the usefulness of the proposed interface modeling.
