| Abstract: | To address the ongoing efforts to virtually design complex composite materials and theirhigh-performance structures and to contribute to the increasing developments towards Industry 4.0,research and development of fiber-reinforced composites is shifting from an experimental domain to avirtually controlled environment. Material models to account for the specific failure mechanisms oflayered fiber-reinforced materials have been developed and can be used for largescale numericalstructural simulations. However, these models do not account for the individual properties of thereinforcing materials and therefore lack information on microstructural effects and behavior. A near-microscale approach for modeling textile and fiber-based reinforcement structures is presented thatallows studies based on the individual textile structure. The digital beam approach is well established inliterature for modeling textile processes and textile unit-cells. It allows simulations where the parametersof the manufacturing process are considered, and the resulting reinforcement structure is obtainedbecause of these simulations. This paper addresses such microscale geometric models of reinforcementtextiles for use in a virtual composite development chain. The resulting mechanical properties can bepredicted for the dry reinforcement textiles by virtual testing and are available as material inputparameters for further investigations, such as textile drape simulations. In addition, an approach ispresented in which the textile models are used directly for composite modeling. Superimposed modelsare presented that take advantage of LS-DYNA's ability to Lagrangian-couple solids and provideinformation about the mechanical behavior of textile-reinforced composites. In addition to thehomogenized mechanical properties, additional information such as load distribution within the fibers andother properties based on the specific design of the reinforcement textile can be derived and analyzed. |
