Empa - the place where innovation starts
Empa is the research institute for materials science and technology of the ETH Domain and conducts cutting-edge research for the benefit of industry and the well-being of society.
Our Laboratory Experimental Continuum Mechanics is offering a
PhD / Postdoc position in the field of microstructure and mechanical behaviour modelling of metallic AM materials
The research project aims to use cellular automata (CA) approach for prediction of the microstructure and texture of selectively laser melted gas turbine blades made of a Ni-base superalloy. Surrogate modelling (machine learning) will be employed for moderating the computational cost of CA for the component-scale simulations. The outcomes of the microstructural simulations will be exploited by an FE-based crystal plasticity model for assessing the high-temperature creep-fatigue deformation and failure of the turbine blade.
A set of laboratory test pieces will be printed and characterised in term of microstructure, texture and mechanical response to generate input data for calibration of the CA and crystal-plasticity models. The verification of the modelling approach will be based on observations from microstructure and mechanical response of the printed turbine blade.
We are looking for a highly motivated team player ready to work independently. The ideal candidate possesses an MSc or PhD degree in materials science, mechanical engineering or related fields. The candidate should have a sound basis in numerical modelling. Prior experience in microstructure modelling, crystal plasticity and machine learning is an advantage. Excellent communication skills and good verbal and written knowledge in English are a prerequisite. Knowledge of German is considered advantageous. The position is available upon agreement.
