PSi RESEARCHER PROFILE
Dr PAYAM SOLTANI
Research Associate- PSi Theme 9
1. Tell us a bit about yourself?
I started my academic and research career in 2001 as a university lecturer in the mechanical engineering field with teaching different courses and supervising several final research and industrial projects. I received my PhD in 2012 mechanical engineering from Ferdowsi University of Mashhad and on the nonlinear modelling of nanostructures. Afterward, I joined the Structural and Material Computational mechanics (MSC) research unit at BATir department at the University of Brussels (ULB). In BATir, I started working on an industrial project with the aim of design, simulation and manufacturing a low-frequency acoustic emission broadband sensor for vibration monitoring of rotary machines.
After this project, I joined the Space Structure and Systems Lab (S3L) at the University of Liege (ULg) as a post-doctoral researcher designing the piezoelectric vibration absorbers with the focus on the nonlinear aspects was my main task during my cooperation with S3L. Now, I am a postdoctoral research associate of the Dynamic Research Group (DRG) at the University of Sheffield and also a member of theme 9 in the Programme for Simulation Innovation (PSi).
Nonlinear dynamics, Finite-Element Modelling, computational mechanics and simulation of the smart materials and structures are my main research interests. A list of my publications and research activities can be found here.
2. Tell us about your role in PSi and what have you been working on?
As a RA on theme 9, I am working on a project titled “Cradle-to-Grave Life Cycle Prediction of Automotive Materials and Systems in Service." My main focus is on the modelling of the material deterioration and ageing of polymeric and elastomeric components in a vehicle. As the ageing gradually changes the mechanical properties of the components, I am also interested in the impact of the ageing on the performance of the vehicle. I am developing a simulation tool for prediction and assessment of two key components during their in-service life. In simple words, I am trying to create a simulation package which predicts the variation of the mechanical and dynamical behaviours of the two key vehicle components as their constituent elements deteriorate during their lifetime.
3. What has been your biggest challenge on PSi?
Material ageing inherently is a complex phenomenon. It occurs in the microstructural scales, but during the lifetime of the component, it might cause a meaningful change in the macro mechanical behaviour. My biggest challenge on PSI project, is finding an appropriate and reliable way to link the measurable mechanical behaviour of the components and also the performance of the vehicle to the micromechanical ageing of the materials. This will lead to creating a comprehensive simulation tool which can imitate the ageing behaviour of the components, and will help automotive engineers to optimize their designs according to the ageing.
4. What lessons have you learnt from working on PSi?
Achieving the valuable goals in the engineering world, will be always possible in an effective team-working environment, with a close and precise collaborations between the academic researchers and the industrial experts.
5. How will PSi help your career?
PSi has brought me the chance to meet and interact with a large number of automotive experts and academic researchers with different expertise, research interests and experience. This will help me develop and expand my engineering knowledge and prospective, especially in the area of the modelling and simulation.
