Job description

We are looking for a highly creative and motivated postdoctoral candidate to join Mechanics of Materials section at Eindhoven University of Technology (TU/e). The position is in the group of prof. Marc G.D. Geers, and will be co-supervised by Ron H.J. Peerlings and Ondrej Rokos.

Context. Metamaterials owe their name to unprecedented effective behavior that typically cannot be found in natural materials, such as being ultra-stiff & ultra-light, having auxetic behavior, or negative compressibility. Such behavior typically emerges from metamaterials' micro-structural morphology rather than from the properties of individual material constituents. Recent trends in metamaterial design aim at their actuation, using, e.g., discrete mechanical, pneumatic, thermal, chemical, or electromagnetic actuation. Metamaterials thus offer a significant design space, which can be exploited in numerous engineering applications such as artificial muscles, medical robotics including minimum invasive surgery, bio-implants, soft robotics, or self- folding systems.

Objective. The objective of this project is twofold: (i) computational and theoretical modeling, design, and optimization of active mechanical metamaterials; (ii) manufacturing and experimental validation of active mechanical metamaterials and devices, building prototypes and unit cells, including casting, 3D printing, actuation, and miniaturization.

Implementation. The first objective revolves around building and implementation of multi-physics first-principle microstructural models, their implementation into homogenization models, i.e., computational exploration of the available design space. The second objective consists in manufacturing of metamaterial unit cells with theoretically proven actuation mechanisms, and measurement of expected effective properties. Manufacturing of entire metamaterial-based assemblies will follow.

Exposition. During the execution phase of this project, the candidate will be exposed to, gain understanding, and deepen knowledge in concepts such as nonlinear coupled multi-physics modeling and simulation, advanced numerical and optimization tools including topology optimization, multiscale computational homogenization, finite element modelling, and machine learning. Experimentally, techniques including manufacturing and 3D printing, microscopy and full-field measurement techniques such as digital image correlation will be involved. Throughout the project, a close collaboration with PhD and master students will be possible and welcome for successful implementation. Although not required, assistance in teaching is possible as well.

Section Embedding. The research will be embedded within the section Mechanics of Materials (www. tue.nl/mechmat), whose activities concentrate on the fundamental understanding of various macroscopic problems in materials processing and forming, emerging from the physics and the mechanics of the underlying material microstructure. The main challenge is the accurate prediction of mechanical properties of materials with complex micro- structures, with a direct focus on industrial needs. The thorough understanding and modeling of ‘unit' processes that can be identified in the complex evolving microstructure is thereby a key issue. The group has a unique research infrastructure, both from an experimental and computational perspective. The Multi-Scale Lab allows for quantitative in-situ microscopic measurements during deformation and mechanical characterization, and it constitutes the main source for all experimental research on various mechanical aspects of materials within the range of 10-9–10-2 m. In terms of computer facilities, several multi-processor-multi-core computer clusters are available, as well as a broad spectrum of in-house and commercial software.

Job requirements
  • Highly talented and enthusiastic candidates with excellent analytical skills are encouraged to apply. A strong background and expertise in computational and experimental techniques for mechanical engineering are beneficial. In particular, candidates with degrees from Mechanical Engineering, Physics, Materials Science, or Applied Mathematics are encouraged to apply. The ideal candidate has excellent scientific skills with a research-oriented attitude, outstanding verbal and written communication skills, and is fluent in spoken and written English.
  • Conditions of employment
  • A meaningful job at a dynamic and ambitious university with the possibility to present your work at international conferences.
  • A full-time employment for 1.5 years.
  • To support you during your postdoctoral stay and to prepare you for the rest of your career, you will have free access to a personal development program for postdoctoral researchers (PROOF program).
  • A gross monthly salary and benefits in accordance with the Collective Labor Agreement for Dutch Universities.
  • Additionally, an annual holiday allowance of 8% of the yearly salary, plus a year-end allowance of 8.3% of the annual salary.
  • A broad package of fringe benefits, including an excellent technical infrastructure, moving expenses, and savings schemes.
  • Family-friendly initiatives, such as an international spouse program, and excellent on-campus children day care and sports facilities.
  • Information and application
