The increasing complexity and demands on modern composite aerospace structures necessitate the integration of multiple assessment steps into a cohesive digital workflow during virtual product development. Traditional approaches often result in fragmented solver-specific data, duplicated efforts for various simulation tools with the resulting inconsistencies or recurring implementations of the same functionalities for different software products. To address this challenge we propose a common \gls{acr:DSL} for computational structural mechanics to bridge the gap between various simulation methods. This \gls{acr:DSL} enables seamless coupling of different assessment steps by means of adapters to commercial simulation software, allowing for the efficient reuse of information and minimization of redundant implementations. We present approaches and examples how a software eco-system surrounding this standard can facilitate the coupling of digital design \cite{LangeF2021}, virtual manufacturing \cite{RaedelM2021} and testing \cite{HollmannR2021} methods of composite aerospace structures. Therein, we address functional implementations for the preparation and transfer of data from different sources, e.g. other simulations and experiments. By demonstrating the feasibility and effectiveness of our approach, we aim to contribute to the advancement of virtual product development in the aerospace industry, ultimately enhancing the design, performance, and efficiency of complex composite structures and risk-mitigation in virtual product developments by early insights into the structural behaviour during manufacturing and testing.
