The main goal is to formulate a multiscale model for relating the macroscopic mechanical behavior of sponge-like particle suspensions to the particle arrangement and their sizes in dynamic situations. This encompasses extending usual Brownian Dynamics schemes to account for the sponginess of the particles, and to simulate the behavior of such suspensions in quiescent conditions and flow situations. In order to formulate a constitutive relation for the macroscopic stress in terms of the microstructure, nonequilibrium thermodynamics (GENERIC framework) shall be used. So doing, the mutual coupling of the mesostructure and the macroscopic behavior shall be implemented consistently. Talented, enthusiastic candidates with excellent analytical and communication skills holding a university degree (M.Sc., Diploma) in Mechanical Engineering, Physics, Materials Science, or a closely related discipline are encouraged to apply. Preferably, you should have experience with several of these topics: mechanics of materials, thermodynamics, transport processes, and computer simulations such as Brownian Dynamics simulations. Fluency in spoken and written English is essential.
