- This paper presents for the first time a two-scale finite-element-based approach for designing tapered laminates that are resistant to delamination onset from ply drop-offs. The latter can cause interlaminar cracking in regions with thickness transitions. The work was funded via the UoB EPSRC "Impact Acceleration Account" (£130k), together with Rolls-Royce plc, as a follow-up activity of Dr Allegri's EPSRC first grant (EP/H040188/1 - £125k). The approach has been implemented as a custom plug-in to the commercial FE software Abaqus and transferred to Rolls-Royce, where it is employed for the design of composite aero engine components.
