Abstract

A Fan Blade Out (FBO) event, in which a fan blade detaches from an aircraft engine, represents a rare but potentially catastrophic loading scenario that places extreme demands on surrounding engine structures. Accurately simulating such events requires reliable constitutive models capable of capturing the complex, rate-dependent behaviour of advanced composite materials under highly dynamic conditions. The aim of this project is to develop and implement constitutive material models for 5-harness satin and braided composite materials and to integrate these models into explicit finite-element simulations of FBO scenarios. The work will be carried out in close collaboration with MSc students, providing hands-on training in material modelling, numerical simulation, and high-performance computing. The project is led by an adjunct professor at Linköping University and is closely connected to industrial practice through full-time employment at GKN Aerospace, ensuring both academic relevance and practical applicability.
