| Abstract Scope |
Three-dimensional textile composite materials are seeing greater use in aerospace and automotive structures. There are many advantages to using these complicated textile composites. However, these 3D woven textile composites introduce additional complexities compared to other composite product forms such as many potential weave structures within a single composite part. While modeling every tow within a coupon may be possible it quickly becomes intractable when considering composite parts. A balanced solution utilizing enough fidelity in critical regions and homogenized properties must be considered for larger and more complicated composite parts. Discrete Damage Modeling (DDM) and Independent Mesh Method (IMM) have been previously applied to complicated 3D textile geometries to derive performance and strength predictions for unnotched coupons and notched coupons loaded in tension and compression. This work will apply DDM and IMM to additional 3D textile-based composite parts. These composite parts add additional geometric complexity and failure modes compared to previous efforts. The models of these composite parts will employ a global-local approach to balance the meso-scale fidelity needed for determining damage and failure and macro-level response. The load-displacement results will be quantitatively compared to experimental results and a qualitative comparison of failure mechanisms between simulation and experiment will be discussed. |
