Abstract The development process of an aircraft fuselage today shows a complex workflow from the first concept phase to the actual operational phase. On one hand, this has a direct impact on the efficiency of both the short-term ramp-up of aircraft production and long-term robustness. On the other hand, this prevents disruptive ideas for innovative architectures with integrated functionalities that enable significant mass savings, cost reduction, increased operational efficiency and the reduction of $$\hbox {CO}_2$$ CO 2 and NOx emissions. The ICASUS (ICASUS-Integrated Cabin-Airframe-System Fuselage, funded by European Joint Undertaking Clean Sky 2 No. JTI-CS2-CPW-LPA-02-01.) project focuses on the development of disruptive concepts and methodologies for an integrated airframe architecture in the cabin/cargo system and fuselage. For this purpose, an integrated approach was developed throughout the entire fuselage from the initial concept to the final operational phase, which directly takes into account several future functionalities and complex requirements from different disciplines. Technologies for future multifunctional structures have been developed to be applied to large-scale modules, future aircraft factories and customization aspects. Furthermore, the development of a novel thermoplastic material was significantly supported by DLR's (DLR-Deutsches Zentrum für Luft- und Raumfahrt e. V./German Aerospace Center.) simulation and experimental material and subcomponent tests. This paper provides insights into numerical investigations of lapshear specimens subjected to impacts with varying energies. The main focus was on simulating the impact itself, as well as conducting subsequent fatigue and residual strength analyses.
