Mohamed Sahbi Loukil

Senior Associate Professor

I have many years of experience in R&D related to polymer composite materials. Characterization of mechanical properties and damage in lightweight composite structures, under quasistatic and fatigue loading, is my main area of expertise.

Expert in characterization of damaged composite materials for aerospace applications

I am Associate Professor at Linköping University, with 11 years of experience on research and development related to polymer composite materials. My area of expertise is characterization of mechanical properties and damage in lightweight composite structures using Destructive, Non-Destructive Testing methods (NDT) and Finite Element Method (FEM).

My work with composite materials has started with my master thesis where I studied micro-damage initiation and growth in laminated composites under thermo-mechanical loading using destructive testing. The continuation of that work was the subject of my PhD.

The years after graduating PhD studies have been very productive for me in terms of international networking and research collaboration. Apart from participation in conferences and workshops I have established an active collaboration with Small and Medium-sized Enterprises (SMEs), big companies, research institutes and Universities. I have been leading several national and European projects and working in close collaboration with SAAB and AIRBUS.  From October 2013 to May 2021, I worked at RISE SICOMP as a research engineer and then as a senior scientist in fatigue of composite materials. In 2018-2019, for a duration of 14 months, I acted as group manager at RISE SICOMP.

My research work has been presented in total of 13 peer-reviewed scientific journal papers, 9 peer-reviewed conference papers and more than 23 international conference presentations.

I co-supervised one PhD student (thesis defended in June 2019) and I am currently co-supervising two PhD students. I have also supervised several master/bachelor theses.

In September 2019, I got my Docent degree in Engineering Materials from LiU. Since June 2020, I am a member of Innovative Materials Arena (IMA) Scientific Advisory Board in Linköping.
