PhD student position in Multiscale modelling of textile composites using Isogeometric Analysis

Updated: 8 months ago

Do you want to work with modern material modelling and finite element analysis of high-performing composite materials? Then please apply to the project "Multiscale modelling of failure in thin-ply textile composites using Isogeometric Analysis".

Project description
The main purpose of this project is to develop and apply a computational multiscale framework that can predict initiation and evolution of relevant failure mechanisms in textile composites. To do so, we will exploit the concept of Isogeometric Analysis and its two benefits of 1) higher order continuity of the in the approximation fields and 2) the straightforward way to adapt the kinematics to model nucleation and growth of cracks. The first part of the project will be focused on developing an efficient shell element formulation based on isogeometric analysis that can describe any number of delamination cracks in a laminated composite. The second part of the work will be devoted to developing representative so-called meso-scale models of the material structure that are able to describe relevant damage mechanisms in each layer. In this part of the work, geometrical information of the material system obtained by CT scans will be translated directly into the numerical model. Finally, in the third part, we will connect the scales between the efficient shell formulation and the meso-scale models by developing appropriate scale-bridging techniques such that information from the rather detailed meso-scale models can be used to analyse larger, thin-walled composite components (using the efficient shell element from part one).

The PhD position is to be placed at the division of Material and Computational Mechanics. The activities of the division are focused on the mechanical modeling of structures, components and processes along with the involved materials, thereby providing mechanics-based solutions and virtual solution tools to our engineering challenges. Currently, about 15 PhD students are working within our main research areas: Lightweight materials and structures, Multi-phase materials, Process modelling and simulation, Railway mechanics, and Structural mechanics.

The current project is run in collaboration with Joris Remmers, Associate Professor in the internationally well-known group of Mechanics of Materials at Eindhoven University of Technology in The Netherlands. Therefore, depending on the interests of the successful candidate, some of the project work could be carried out in that group.

Department of Industrial and Materials Science

The main competencies at the Department of Industrial and Materials Science are found in the areas of: Human-Technology Interaction | Form and Function | Modeling and Simulation | Product Development | Material | Production and in the interaction between these areas. The research develops the industrial process, from need to finished product while creating added value. To combine skills throughout the whole chain distinguishes the department both nationally and internationally. Here we gather internationally prominent researchers, in dynamic and outstanding research environments, as well as in national and international research networks.

Major responsibilities
Your major responsibility as a PhD student is to pursue your own doctoral studies related to the project. This includes developing scientific concepts and communicating research results both verbally and in writing. Your research activities will contribute to enhanced knowledge in the scientific field, in particular by presenting your results in scientific journals and at international conferences.

In addition to the research project, you will also take courses on the advanced level within the graduate school of Solid and Structural Mechanics. The position also includes departmental duties, such as teaching, corresponding to about 20% of working hours. You will be employed by Chalmers.

Position summary
Full-time temporary employment. The position is limited to a maximum of five years.

The successful candidate for this position has a MSc in Applied Mechanics, Engineering Mathematics, Structural Engineering, Engineering Physics or similar with an emphasis on solid/structural mechanics and computational methods. Very good knowledge in solid mechanics, continuum mechanics, material mechanics and the finite element method (including programming thereof) is required. Furthermore, meriting educational experience is that in computational mathematics, numerical analysis and object-oriented/high-performance programming. Also, knowledge in the theory of deformation and fracture mechanisms in composites is a strong merit.

Since communication of research results is a central part of the work, communicative skills in English (oral as well as in writing) is vital. Furthermore, it will also be expected that you can take on responsibility and have the ability to take own initiatives and, when needed, work independently. At the same time, being a successful researcher also involves working with others as well as disseminating the results within existing and new networks, both within academia but also to industry and society, whereby networking skills, team work skills and quality assurance abilities are important.

On a personal level, we expect that you are motivated to pursue a research education, that you are self-propelled and quality conscious.  Furthermore, as the project will be theoretically advanced and will involve programming, we expect that you have strong analytical skills and an interest in coding.

Knowledge of the Swedish language is desirable but not a requirement. Chalmers offers Swedish courses. To qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits in a relevant field. Finally, additional meriting factors include technical development and research project skills, journal publications and industrial employment or similar experience.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
