Background
Dr Wenli Liu is a Lecturer in Structural Integrity and Design, and, in addition to being a highly qualified academic, she has gained practical research and design experience in the aircraft industry over the past 20 years.
In 1993, after obtaining her first degree in Aircraft Structures from the Northwestern Polytechnical University (NPU), Xi’an, China, she was recruited to work for five years as a Stress Engineer for the Chinese National Aircraft Structural Strength Institute. She then returned to university to complete two higher degrees: her MSc in Aircraft Design in 2001 from NPU, Xi’an, China, and in 2005 her PhD in Aerospace Composite Structures from the University of Bath, in the UK.
Wenli successfully received funding by the EPSRC as a post-doctoral researcher working on optimisation, manufacture and damage tolerance analysis of novel composites for aircraft application (2005-2007 and 2010-2013). Airbus funded her for two years secondment (2007-2009) at their Filton industrial site to develop an integrated design method for whole composite aircraft wing layout.
Dr Liu’s main research interests include Finite Element modelling of composite structures and failure, structural optimisation, automated fibre placement and tow steering, buckling and postbuckling of stiffened wing panels and fuselage.
