Numerical analysis of curved composite using cohesive zone modelling

This paper presents the finite element (FE) analysis of top hat stiffeners (manufactured using vacuum assisted resin transfer moulding (VARTM)) under static load where laminate splitting/delamination is the primary mode of failure. A set of experiments are conducted on composite top hat stiffeners with three different layup arrangements. The experimental study together with FE modelling to capture the delamination failure is presented.
