Offer Description

Section description

The research activities of the section Mechanics of Materials concentrate on the fundamental understanding of various macroscopic problems in materials processing, forming and application, which emerge from the physics and the mechanics of the underlying microstructure of the material. The main challenge is the accurate prediction of mechanical properties of materials with complex microstructures, with a direct focus on industrial needs. The thorough understanding and modelling of ‘unit’ processes that can be identified in the complex evolving microstructure is thereby a key issue. The section has a unique research infrastructure, both from an experimental and computational perspective.

The overarching project: ‘Data Enhanced Physical models to reduce MATerials use’ (DEPMAT)

Society calls for an increased recycling of material in steel production processes to reduce the huge CO2 footprint. Current physics-based material models for predicting mechanical properties based on composition and thermo-mechanical history are too simple or too computationally expensive for use in industry. The DEPMAT project aims to develop physics-informed, data-based (machine learning and artificial intelligence) methods for superior accuracy and speed, to enable predictive modelling in industry and to increase recyclability in steel making. We are building a team of talented, enthusiastic researchers to achieve this exciting goal.

PhD vacancy with a focus on Fast micromechanical models for data-enhanced materials engineering

Macro-scale mechanical properties of steels are predicted by high-fidelity numerical models of micro-scale material domains. Representative Volume Elements (RVE) of the multiphase metallic microstructures are generally used for this purpose, in which the individual grains are typically represented by state-of-the-art single-crystal plasticity models. Their input generally consists of the phase distribution in space, orientations of the individual crystals, chemical composition of the phases, etc. The main output of interest is the mechanical behaviour of the (in silico) material. The significant computational cost of these numerical models is due to the complexity of the (three-dimensional) microstructural geometry and constitutive modelling, together with the fine spatial and temporal discretization required to solve them. The goal of this numerical PhD project is to speed up the micromechanics simulations substantially (at least two orders of magnitude), at the cost of some (but not too much) of the fidelity of the detailed modelling. This acceleration of the RVE models is to be achieved by combining dedicated computational reduction methods akin to reduced order modelling to exploit the similarity of different realizations of statistically similar microstructures with careful idealization of the microstructural geometry and constitutive behaviour – e.g. where possible eliminate irrelevant details from the geometry, exploit symmetries, replace crystal plasticity by isotropic plasticity, replace (coupled) damage models by damage indicators, etc. Each of these reduction methods needs to be carefully assessed.
