Renaud Gutkin works with Research & Development at Volvo Cars Safety Centre and is associate professor at the division of Material and Computational Mechanics at Chalmers University of Technology. His research focuses on the structural response of polymer and composite materials. Renaud received his Ph.D. in Composite materials from Imperial College London, Department of Aeronautics, in 2010. He then worked with nonlinear finite element analysis as a post-doctoral researcher at Airbus UK. In 2011, Renaud joined Swerea|SICOMP (the Swedish institute for polymer composites) where he worked as a Senior scientist in the area of material modelling and later on as Head of the structural analysis team.
Title promotion lecture: Computational mechanics of polymers: from structure to materials, from materials to structure
New technologies together with environmental demands are pushing the automotive industry to constantly increase their efficiency in developing new, sustainable and innovative solutions. Polymer and Composites are therefore increasingly used in demanding and tougher applications. Simulation tools and Computer Aided Engineering (CAE) are key elements in developing safer and more durable products in an efficient way. However, CAE of polymeric materials is a challenging area since polymers and composites show a wide variety of properties, mechanical responses as well as complex microstructures.
In a first part, this lecture will look at the challenges faced to correctly analyse polymer and composites in an industrial environment and large structural models: from structure to materials. In particular, we will discuss material models and numerical methods developed to analyse structures subjected to crash or strength events but also subjected to temperature loads. Emphasis will also be made on the role experimental material characterization plays in establishing reliable models. Some challenges related to coupling analyses from process simulation, by external loads simulation and to structural simulation will presented by looking at an holistic CAE chain for temperature loads.
In a second part, from materials to structure, we will look at how structural analysis can in its turn be used to analyse the micro or meso structure of composite materials, enabling their behaviour to be predicted and opening the way for virtual material testing.
