GARTEUR AG-37 focuses on the characterization and optimization of innovative shock absorbing devices for aerospace and industrial applications. The motivation of the Action Group is related to the need for lightweight structural concepts capable of mitigating impact and crash loads, while reducing mass and improving integration within existing structures. Conventional shock absorbers are often based on solid or thin-walled metallic components, which are robust but may offer limited design flexibility and suboptimal mass efficiency. For this reason, the AG investigates lattice-based and hybrid solutions, in which the geometry of the absorber can be tailored to promote progressive deformation and efficient energy dissipation.
The AG addresses the development and assessment of feasible shock absorber concepts, combining structural design, modelling and experimental validation. Particular attention is devoted to additively manufactured lattice structures, hybrid metal/composite configurations, and the role of key design parameters such as lattice topology, beam diameter and skin thickness. The activity supports the understanding of deformation mechanisms, damage evolution and energy absorption behaviour under impact loading, with the aim of identifying promising configurations for lightweight and manufacturable shock absorbing structures.
The AG brings together partners with expertise in structural design, numerical simulation, impact testing, additive manufacturing and composite materials.
