Vibro-acoustic behavior of lightweight and meta-materials
KU Leuven, Belgium
Deadline: Sat, 31 Oct 2015

Project
In the global trend towards more CO2 efficient products, e.g. in the transport, energy, or industrial machinery sector, mass reduction is key. Typically, lightweight solutions are detrimental for good NVH behaviour, as low noise and vibration levels go hand in hand with mass. As such, KU Leuven is investing a substantial research effort in the dynamic behaviour of these novel types of materials, both in simulation and testing, allowing for a better design and optimisation thereof.

Novel wave based simulation techniques as well as acceleration methods for element based techniques are developed and validated in view of efficient vibro-acoustic simulations over the full audio frequency range that enable to account for the effects of uncertainty and variability. Coupling strategies are explored to allow the efficient and effective integration of vibro-acoustic models into system-level multiphysics models, where disparate length, time and energy scales come together.

Advanced experimental testing and analysis techniques in combination with inverse methods are developed for accurate and fast dynamic characterisation of (multilayer) materials and structures and for source localization and quantification. These advanced techniques are complemented by a fully equipped noise and vibration laboratory and test rigs which allow easy and fast experimental evaluation of the dynamic properties of interest.

Another emerging line within the research activities of the group focusses on intelligent structures that exhibit vibro-acoustic stop-band behavior such that the combination of low mass with good noise and vibration performance comes within reach for engineering applications. First physical realisations prove the potential of these so-called acoustic resonant metamaterials to take sound insulation to a next level (http://youtu.be/hMCfRHshjXc

The Noise and Vibration research group is looking for different profiles to join the team on vibro-acoustic analysis of lightweight structures and materials. We are looking for researchers with a numerical simulation background as well as people with a more experimental testing background. As well research engineers, PhD students as postdoctoral researchers are welcomed to apply.

Profile
We are looking for highly motivated, enthusiastic, communicative and eager to learn researchers with a Master of Science in Engineering (preferably in Mechanical or Electrical Engineering). The candidates should have a strong background and interest in vibro-acoustic analysis and lightweight structure design.

PhD student Modeling and Simulation of the 3D-Printing
Eindhoven University of Technology, Netherlands
Deadline: Wed, 30 Sep 2015

The focus of this study is to examine the underlying principles for achieving certain particle arrangements by electromagnetic fields in 3D printing, discussing the feasibility and limitations of the process, by means of modeling and computer simulation. Particularly, the competition between the dynamical arrangement of the particles by the imposed electromagnetic field and the fixation of the particle arrangement (by photocuring) is crucial. A suitable modeling approach must therefore combine aspects of the mechanical behavior of the matrix material (fluid before curing, semi-solid during curing), the migration and re-arrangement dynamics of the filler particles under the influence of the imposed field, as well as the photocuring itself. By modeling and simulation, the design principles and useful guidelines will emerge, that will foster the development of this class of 3D-printed multifunctional objects. There will be close interaction with experimentalists working on 3D printing. While this project is mainly theoretical, it is desirable that the proof-of-principle is made within this project.

Job requirements
We are looking for a candidate who meets the following requirements
Master degree in mechanical engineering, physics, materials science, chemical engineering, or related field
Strong interest in modeling and simulation research
Ability to approach problems in an analytical and organized way
Good communication skills in English, both written and oral

PhD in Microstructures
Delft University of Technology, Netherlands
Deadline: 16-10-2015

Job description
Recent structural developments in the field of composite 3D printed structures have led to a patent application for micro frame structures, a kind of indeterminate truss structure. One of the key characteristics of such a micro frame is that trusses have many connections to other truss elements, giving them the capability to be loaded and unloaded over a greater length. Another key characteristic is that the structural elements are highly loaded (for instance a stress level of 1000 MPa). The multiple connections to structural elements facilitate the load transfer to get to these high stress levels. The manufacturing of such a micro structure is envisioned on a modified 3D printer in cooperation with a robot arm.

In the context of this research, the Structural Integrity and Composites research group is seeking a PhD applicant who will develop optimisation routines for topology optimisation applicable to these micro frame structures, utilising the limits of load transfer per connection and feasibility of manufacturing.

Requirements
We expect the candidate to hold an MSc degree and have a strong affinity for composites and load transfer as well as an interest in both numerical and experimental work. Applicants should have an open personality and good English language skills in order to closely cooperate with colleagues and students as well as write research papers.
Conditions of employment

For more information about this position, please contact Dr. Otto Bergsma, phone: +31 (0)15-2785135, e-mail: O.K.Bergsma@tudelft.nl. To apply, please e-mail a detailed CV and references along with a letter of application by 31 October 2015 to Gemma van der Windt, G.J.M.vanderWindt@tudelft.nl.
