Delamination in composite laminates is basically an interfacial crack between two orthotropic materials possibly oriented in different directions. One of the characteristics of interfacial cracks between two dissimilar materials is the oscillatory behavior of the stress field near the crack tip [

]. Classical fracture mechanics has been adopted for modeling delamination in composite materials; stress intensity factors are commonly used to characterize delamination fracture toughness. In using fracture mechanics with the stress intensity factors, one must make sure that the near tip singular stress field be dominant in the fracture process zone
