Beschreibung

The development of complex materials with tailored properties, as well as the understanding of the underlying mechanisms require reliable high-throughput simulation tools, that can be combined with data analytics and material characterization.

This will allow to predict the structure-property relation and to understand and evaluate experimentally obtained data sets.

As a PhD student you will work at the Institute for Advanced Simulations - Materials Data Science and Informatics (IAS-9) where we combine data analysis, materials simulation, research data management and software development under one roof.

We also benefit from a strong connection to the Ernst-Ruska-Centre for Electron Microscopy and to the Jülich Supercomputing Centre.

As such, we can provide a multidisciplinary environment during your research that will help to develop your competencies in a range of scientific fields.

Your Job:

The field of micron-scale plasticity is particularly interesting as size-dependent behaviour, intermittency and far-from-equilibrium processes directly show in the resulting mechanical properties.

At this length-scale simulation methods such as Discrete Dislocation Dynamics are becoming capable of modeling the evolution of the entire microstructure and, thus, can help in understanding such technologically rather relevant phenomena.

One of the open challenges to understand is why and when dislocations show scale-free avalanche behaviour, and whether these events can be predicted.

To this end, dislocation simulation tools have to be developed and applied, combined with various methods from the field of data science.

The main goal is to provide physical understanding of the novel experimental findings of our international research partners we are in close contact with.

As such, the position offers the opportunity to be involved in fruitful international collaborations.

In this exciting job you can expect:

to model stick slip motion of a single dislocation in high entropy alloys, to explain the development of the fractal-like dislocation shape

- to simulate how acoustic emission signals are being generated during sudden collective dislocation avalanches
- to provide statistical analysis of simulated discrete dislocation structures and to transform them into AI- and ML-ready information
- to contribute to the development and improvement of discrete dislocation dynamics simulation software
- to publish and present research results in relevant journals and at international conferences

Your Profile:

A completed university degree (Master or equivalent) with excellent grades in the field of mechanical engineering, material science, physics, computational science or similar, preferably with a specialization in the field of theory and/or simulation
Practical experience in at least one programming language (preferably C++ and/or Python) and experience with the use of Unix/Linux operating systems
Experience in scientific code development involving numerical analysis methods, parallel computing and optimization
Structured and analytical thinking as well as a systematic, careful, independent, and reliable working method
Interest in working closely with experimentalists
Strong cooperation and communication skills and the ability to work as part of a team
Excellent written and spoken English skills

Our Offer:

We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change We offer ideal conditions for you to complete your doctoral degree:

The opportunity to conduct exciting research in an international and multidisciplinary environment with outstanding infrastructure
The opportunity to gain your reputation in a dynamic and highly active research field
The opportunity to attend national and international conferences
Flexible working hours and various opportunities to reconcile work and private life, as well as 30 days of annual leave
Targeted services for international employees, e.g. through our International Advisory Service
