Research Projects

ENFASSENhanced Formability Assessment of AHSS sheets. In this project the influence of stretch-bending on the formability of AHSS is investigated. The industrial partners of this project are Voestalpine Steel (Austria), Tata Steel Technology (The Netherlands), Daimler AG (Germany), Virtual Vehicle (Austria)
TAPAS (concluded)The Thermoplastic Affordable Primary Aircraft Structure consortium. In UT the main task is to develop an efficient optimization algorithm for the ply orientations in fibre-reinforced laminated composites in order to reduce weight while satisfying the constraints on the stiffness of the panels. The partners in this project are Airbus, Airborne Technology Centre, Dutch Thermoplastic Components, KVE Composite Group, Stork Fokker AESP, Technobis Fibre Technologies, TenCate Advanced Composites, Technical University of Delft

PhD-Research

I obtained my PhD degree in the Applied Mechanics group at the University of Twente with my dissertation titled ‘Constitutive modelling of metastable austenitic stainless steel’ . During this research I developed a novel physically-based constitutive model that predicts the mechanical behaviour of the metastable austenitic stainless steel which undergoes mechanically-induced martensitic transformation during deformation.
