Structural analysis of fiber-reinforced composite structures using finite element analysis (FEA) are usually performed using shells due to the complexity in modeling the layers of the composite structure with 3D elements. However, accurately modeling the residual strength of composites require incorporating concrete definition of defects into layered 3D models, which is not directly feasible with shells. In this work, we have developed an automated framework that can first be used to isolate a region of interest from a shell computer-aided design (CAD) model of a composite structure, model the individual layers in the region, incorporate defects such as delaminations and fiber breakage, and set up the model for structural analysis using FEA. This framework can be used to automatically set up structural analysis of a composite structure with defects and accurately assess the impact of manufacturing defects or service damage on its residual life.
