|Summary||Theoretical approaches based on bridged-crack models and plate/beam theory have proved to be effective in the modeling of Mode I and Mode II delaminations in composite laminates reinforced through the thickness. This paper deals with some aspects of the modeling of Mixed Mode delaminations. Two typical mixed mode problems are considered: the curved beam in bending (C specimen) and the Mixed-Mode Bending specimen (MMB) reinforced through the thickness.
||Keywords|| delamination, mixed mode, stitching, energy release rate, crack bridging, beam theory.
