An Integrated Modeling Scheme for Sensor Embedded Woven Composite Structures in Manufacturing Simulation
This work focuses on an integrated modeling scheme of a sensor embedded woven composite structure which is created for the joint project “Digitaler Fingerabdruck” (DFA) or in English: “Digital Fingerprint” within the research campus ARENA2036 [4]. The process chain includes a draping simulation of a woven fabric and a trimming simulation using LS-DYNA®, optimization of a tailored-fiber placement process on top of this woven fabric structure using Optistruct®, fiber direction mapping from weaving simulation results using beam elements to shell element target meshes and handling of reinforcing patches using the mapping tool Envyo® [5]. The final goal is to establish an integrated process chain with parametrized variables using LS-OPT® for robustness analysis. A new feature of *MAT_REINFORCED_THERMOPLASTIC (*MAT_249) is also demonstrated to introduce fiber directions as an integration point history variable in global coordinate system to the subsequent simulations [7].
