This PhD is part of a project on multiscale modeling of composite materials. The overall objective of the project is to predict how much energy is required to grow cracks in composite materials. Improved understanding of the dissipative processes in composites can lead to more optimized usage of this material in various engineering applications. The envisioned multiscale finite element approach is associated with very high computationally cost, because of the large number of micromechanical simulations involved. Therefore, acceleration of the micromodel is an essential part of the project.
This PhD will focus on acceleration of micromechanical analysis by defining an efficient surrogate model based on reduced order modeling or machine learning techniques. Such techniques are becoming available in the context of finite element analysis, but their applicability for the problem at hand still needs to be established. The researcher will explore available techniques and optimize them to speed up the relevant nonlinear micromechanical simulations.
Applicants should possess a relevant MSc degree in a mechanics-related discipline (civil/mechanical/aerospace engineering), applied mathematics or machine learning. An aptitude for programming is essential. The successful candidate must be able perform independent research but also interact with others in the project team. Excellent skills in written and spoken English are required. The selection of the candidates will also be based on passion and persistence for doing research and the ambition to develop a research career.
TU Delft offers a customisable compensation package, a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children’s Centre offers childcare and an international primary school. Dual Career Services offers support to accompanying partners. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.
As a PhD candidate you will be enrolled in the TU Delft Graduate School. TU Delft Graduate School provides an inspiring research environment; an excellent team of supervisors, academic staff and a mentor; and a Doctoral Education Programme aimed at developing your transferable, discipline-related and research skills.

Fixed-term contract: 48 months
Delft University of Technology (TU Delft) is a multifaceted institution offering education and carrying out research in the technical sciences at an internationally recognised level. Education, research and design are strongly oriented towards applicability. TU Delft develops technologies for future generations, focusing on sustainability, safety and economic vitality. At TU Delft you will work in an environment where technical sciences and society converge. TU Delft comprises eight faculties, unique laboratories, research institutes and schools.
The Faculty of Civil Engineering and Geosciences (CEG) is committed to outstanding international research and education in the field of civil engineering, applied earth sciences, traffic and transport, water technology and delta technology. The research covers global social issues and is closely connected to education as well as the work of a wide range of knowledge institutions. CEG is convinced that Open Science helps to realise these goals and supports its scientists in integrating Open Science in their research practice. The Faculty of CEG comprises 28 research groups in the following seven departments: Materials Mechanics Management & Design, Engineering Structures, Geoscience and Engineering, Geoscience and Remote Sensing, Transport & Planning, Hydraulic Engineering and Water Management.
In the Applied Mechanics section of the 3MD department, research is performed into the analysis of solids and structures relevant to civil engineering. The research mission of the programme is to provide mechanics-based tools and solutions to civil engineering challenges. Novel computational and analytical techniques are developed for more reliable, efficient and effective analysis of materials and structures. There is a specific interest in new and innovative civil engineering structures and high-performance materials. The research work is fundamental and applied in nature, and has a mono-, multi- or transdisciplinary character. The scientific work should keep pace with the highest level in the international scientific community and with the front line of technical innovations and challenges.
