Postdoc position (2 year) on Computational Modelling of Artificial Cilia

Currently, a 2-year post-doc position is available in the Onck group. 

We are looking for an ambitious candidate with affinity for computational modelling that has completed (or is in the process of completing) a PhD degree in the field of Mechanical Engineering, Aerospace Engineering, Applied Physics or Applied Mathematics. Candidates that have hands-on experience with Finite Element and/or Molecular Dynamics techniques are especially invited to apply.

PhD position available: "Computational Design of Soft Robots"

I have a vacancy with my colleague Prof. Verstappen at the University of Groningen for a PhD student to work on the computational design of magnetically-driven soft robots (see details in the attached description). Candidates preferably have hands-on experience with finite element development and implementation. If you are interested, please send a CV before March 21 at p.r.onck@rug.nl.

Temperature-dependence of mode I fracture toughness of a bulk metallic glass

Bulk Metallic Glasses were found to exhibit an intermediate temperature minimum in ductility. Does it also lead to an intermediate temperature minimum in fracture toughness?

Postdoctoral vacancy (36 months) on patient-specific design and finite element modelling of 3D printed medical implants

3D printing or Additive Manufacturing (AM) technologies carry the promise of revolutionizing the quality and efficiency of healthcare. However, the required technologies, even when available, are currently too fragmented to be integrated into routine, affordable and streamlined solutions that can benefit a large number of patients. The challenge thereby is to deliver 3D printing technologies that enable:

Modelling cyclic behaviour of soil using UMAT

Choose a channel featured in the header of iMechanica: 

I have been trying to model the cyclic behaviour of soil. I got a UMAT. But when I'm using UMAT, it is creating lot many errors (like numerical singularity and excessive distortion). I have constrained it properly. I tried running my model with an inbuilt material (clay plasticity) and I'm getting results. Here I'm not even able to move from the initial geostatic step. Can anyone please help

Materialise & Simulia Medical Engineering Seminar

Materialise and Dassault Systemes Simulia Benelux are pleased to announce their co-organized Medical Engineering Seminar which will take place on 4 October 2011, at the Materialise HQ in Leuven, Belgium. The Medical Engineering Seminar is a meeting for and by users and aims to bring together biomechanical engineers currently working, or interested in patient-realistic finite element modeling.

 

PhD position - Modelling of confinement and interfacial effects in small scale plasticity

The project is based on the well-known size effect exhibited by metals, i.e
the fact that their strengths are greatly enhanced when at least one
microstructural lengthscale is scaled down to the nanometer range or
when the size of the object is restricted to the micron or sub-micron
range. At these scales the interfaces and their associated properties
play a significant role. This project will focus on the effect of
spatial confinement on the three most common deformation mechanisms:
dislocation glide, mechanical twinning and mechanically-induced
martensitic phase transformations; and will be based on the synergies
between physically-based phenomenological modelling using
strain-gradient plasticity at the highest scale, and thorough
