“…Understanding the advantages of material combinations and challenges arising from a wide range of possible parameters is crucial for simulating and determining the process-parameter-structure-property relationships [3,9]. The new approach is to develop and use a DT to help the designing process of a component and to understand the PSPrelations.…”

“…Established design approaches such as VDI-2221 or the QFD approach must be improved and extended to meet these new requirements. Technologies to aid the networking of manufacturing processes and combine them with corresponding simulation and other software tools, have already been investigated [3]. A suitable tool that can be added into this are digital twins (DT) [4,5].…”

The innovation potential of lightweight design in its scientific and technical foundations lies in the systematic, i.e. integrated and cross-material consideration of the process chains. This consideration is one of the main goals of dahlia project - Digital Technologies for Hybrid Lightweight Structures. The end-to-end digitalisation of the development, manufacturing and validation processes provides a first understanding of its process parameter-structure-property relationships, which is essential for developing a representative digital twin. To investigate these aspects in the design phase profiles made of aluminium alloy are exemplarily studied. Important aspects for the development of a digital twin are considered, such as a knowledge-based selection of design and simulation tools, their respective parametrisation and interface communication. First results are presented as well as the development aspects of a digital twin from its nominal offline form up to its specific application at a generic lightweight structure.

“…Novel process chains for intrinsic hybrid structures are given in [74]. The combination of different process steps consequently leads to challenges in terms of integrated simulation methods [75]. At the research factory Open Hybrid LabFactory in Wolfsburg (OHLF), Germany, [76] integrated manufacturing processes for MMLS in high-volume applications are investigated.…”

Within product development processes, computational models are used with increasing frequency. However, the use of those methods is often restricted to the area of focus, where product design, manufacturing process, and process chain simulations are regarded independently. In the use case of multi-material lightweight structures, the desired products have to meet several requirements regarding structural performance, weight, costs, and environment. Hence, manufacturing-related effects on the product as well as on costs and environment have to be considered in very early phases of the product development process in order to provide a computational concept that supports concurrent engineering. In this contribution, we present an integrated computational concept that includes product engineering and production engineering. In a multi-scale framework, it combines detailed finite element analyses of products and their related production process with process chain and factory simulations. Including surrogate models based on machine learning, a fast evaluation of production impacts and requirements can be realized. The proposed integrated computational product and production engineering concept is demonstrated in a use case study on the manufacturing of a multi-material structure. Within this study, a sheet metal forming process in combination with an injection molding process of short fiber reinforced plastics is investigated. Different sets of process parameters are evaluated virtually in terms of resulting structural properties, cycle times, and environmental impacts.
