- This is the first paper to prove the relative importance of different ply-wrinkle parameters (angle, deviation, etc) in governing composite-material compressive strength - crucial to lightweighting for greener aircraft. It links Smith's body of research on ultrasonic wrinkle measurement to Hallett's defect modelling. The outcome allows model-based performance assessment of wrinkled composites, reducing risk and opening up the design envelope. It has improved wrinkle measurements and acceptance standards in Airbus, GKN, Rolls Royce and others. An EPSRC Programme Grant, 'CerTest', is extending this to 'component' scale. A linked conference paper was awarded best paper by the British Institute of NDT.
