I come from Croatia and like to keep things simple as much as possible. I always had an interest in mathematics and physics. Therefore, I enrolled and obtained a master’s degree at the University of Zagreb, Faculty of Mechanical Engineering and Naval Architecture, with specialization in Engineering Modeling and Computer Simulations. During my studies, I covered a wide area of engineering applications, like fluid dynamics, regulation and optimization, but eventually settled with structural dynamics and the finite element method, with my master’s thesis focusing on modeling of nonlinear multiphase materials. My goal is to learn about new implementations of FEM, especially regarding efficiency.

I have interest in programming and believe that the open-source approach is the way to go. Currently, my primary focus is Python, but am looking to extend my programming knowledge and learn other programming languages. I also like to learn new languages, and am currently speaking English, German and just the basics of Japanese.

The reason I applied for this project is because it is a natural extension of my interests and a good opportunity to meet interesting people. In my opinion, this is the perfect opportunity to further improve my skills as well as learn new concepts and, hopefully, develop new approaches in nonlinear dynamics and nonlinear material modeling.

Description

ESR will focus on nonlinear material models and their implementation in nonlinear dynamics within numerical analyses of deployable beam structures for space applications. The ESR will be trained to apply modern techniques for automatic differentiation in development of constitutive material models using symbolic approach that allows to derive accurate and efficient finite element (FE) routines including sensitivities with respect to the wide range of model parameters.

Expected Results

The results will have an impact on a wide variety of advanced space missions utilising deployable precision pointing antennas, solar sails, slender mechanisms for space debris removal and other deployable structures which must be compactly packaged for the limited size of launch vehicles and then expanded automatically in orbit. An optimal design of deployable structures is obtained from appropriate numerical models that assess the dynamic responses to vibrational loads during launch as well as their mechanical behaviour in space and the large geometric transformations.
