Advanced inverse material identification procedures rely on the richness of strain fields generated in a complex specimen, i.e. a so-called heterogeneous experiment augmented with a full-field measuring technique. Currently, the design of such an information-rich experiment is often based on engineering judgement and experience. The latter results in user-specific design of heterogeneous experiments. To cope with the latter, this PhD study ...

The mechanical properties of NbC based cermets are closely linked with the chemical composition of the secondary carbide addition and the carbon content of the NbC phase, as well as the processing conditions. The proposed research is aiming to understand the processing-microstructure-properties correlations of NbC-based cermets, doped with secondary carbides as a function of the metal binder content and (Co, Ni, Fe) composition.

This research focuses on understanding and estimating the effects of residual stresses induced by Wire Arc Additive Manufacturing (WAAM) technique and subsequent corrective machining process on fatigue/fretting fatigue lifetime. To do so, a finite element toolkit will be developed to chain together several manufacturing processes to achieve a final finished product, following the fatigue/fretting fatigue lifetime estimation of the final ...

There is a growing interest in predicting of various mechanical failure modes of infrastructures. The importance of managing ageing infrastructures has gained public’s interest in light of catastrophic incidents. Fatigue phenomenon is one of the complex mechanical failure mode, which occurs in combination of different influential parameters. The application of stress-based criteria for high cycle fatigue or plastic strain-based criteria for ...

AM(Additive manufacture) technology is currently altering many industrial operations, among which many have found applications in medicine, dentistry and so on. However, AM technology is used mostly in fabrication of polymeric or metallic materials, and the processing of ceramics is much more difficult than polymer and metal 3D-printing. So, in my work, exploring the potential of AM to fabricate zirconia restorations will be the most ...

2-dimensional (2D) semiconductors such as 2D transition metal dichalcogenides (MX2) have recently drawn much attention in the field of nano-electronics due to their potential for superior electrostatic control and heterogeneous integration. However, current MX2 devices suffer from high source and drain contact resistance, high defect density and low capacitance/charge build-up in the channel. To mitigate these challenges, it would be ...

I am interested in finding the underlying mechanisms governing the mechanical properties of natural fibers (flax fibers) throughout molecular dynamics simulations both at atomistic and coarse-grained scales. In order to do so, force fields capable of describing the chemical and physical interactions between the basic ingredients of a fibre (cellulose, hemicellulose, lignin, and water) at the atomic and coarse-grained scales must be ...

To perform a stakeholder assessment specify main drivers and barriers as well as risks and benefits of ELFM implementation. To identify the main societal impacts of NEW-MINE ELFM scenarios and quantify their (positive or negative) monetary values based on environmental economics principles and methods. To quantitatively assess the private economic impacts on NEW- MINE ELFM scenarios of new policy measures for internalizing ELFM externalities, ...

Follows from diffuse-interface approach, and it is straightforward to take different driving forces into account, phase-field modeling has a wide variety of applications on the phenomena of solidification, solid-state phase transformations, fracture etc. High Entropy Alloys (HEAs) have potentially desirable properties as a novel material in materials science and engineering. The inter-diffusion phenomena at the material solidification ...
