- This paper presents the development and validation of a novel finite element formulation for predicting delamination suppression via through-thickness reinforcement (TTR). This approach provides for the first time a robust multi-scale modelling capability for composites with TTR, which links the mixed-mode response of individual TTR units with the global structural performance. This has been deployed in the commercial finite element software LS-DYNA via user-defined subroutines and transferred to Rolls-Royce through the InnovateUK funded £18M CTI-FAN (113085) and the £33M FANTASTICAL (113190) research programmes (James.Finlayson@Rolls-Royce.com). This LS-DYNA implementation will be used to design Rolls-Royce’s next generation "UltraFan" composite fan blades.
