The influence of through-thickness reinforcement on Mode II delamination fracture in composite laminates is investigated. The bridging traction law, which characterizes the toughening mechanisms due to the through-thickness reinforcement, is deduced from crack profile measurements in End Notched Flexure specimens. The problem is solved through an inverse formulation of a bridged-crack model based on bending theory for anisotropic plates.

Abstract
The influence of through-thickness reinforcement on Mode II delamination fracture in composite laminates is investigated. The bridging traction law, which characterizes the toughening mechanisms due to the through-thickness reinforcement, is deduced from crack profile measurements in End Notched Flexure specimens. The problem is solved through an inverse formulation of a bridged-crack model based on bending theory for anisotropic plates.
