Abstract: There is provided a method and a system for finite element (FE) analysis of a composite structure comprising plies arranged according to a stacking sequence and layers of bonding agent. Each layer of bonding agent interconnects two adjacent plies. In-plane properties and out-of-plane properties of the composite structure are received. An FE model of the composite structure is generated by representing the plies by two-dimensional (2D) elements configured to be arranged according to the stacking sequence, representing the layers of bonding agent by three-dimensional (3D) elements, each 3D element configured to interconnect two adjacent 2D elements, and associating the in-plane properties with the 2D elements and the out-of-plane properties with the 3D elements. An FE analysis of the FE model is performed to predict delamination of the composite structure.
