PD in “Design of active mechanical metamaterials &their experimental
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-
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.
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.
