multiscale

Applications are sought for multiple Post-Doctoral Research Associates at University of California, San Diego (USA) and Cardiff University (UK) and two PhDs (Cardiff) to join a very active cross-continental M2DO research lab. The primary research focus is to develop topology optimization for multiscale and multiphysics problems optimizing materials and structures. The research members are required to travel between US and UK regardless of their bases.  

Research experience in the following areas are required.

Applications are sought for four Post-Doctoral Research Associates and two PhDs to join a very active research group at Cardiff University, UK (School of Engineering).  Based in Cardiff, there will be frequent interactions with the University of California, San Diego as well as major aerospace companies in the UK. The research will formulate and develop numerical methods for mulitiscale and multiphysics design optimisation using level set topology optimization.

One or more of research experience in the following areas are required.

Spatial pattern formation in stiff thin films on soft substrates is investigated from a multi-scale point of view based on a technique of slowly varying Fourier coefficients. A general macroscopic modeling framework is developed and then a simplified macroscopic model is derived. The model incorporates Asymptotic Numerical Method (ANM) as a robust path-following technique to trace the post-buckling evolution path and to predict secondary bifurcations.

Applications are invited for one PhD position (4 years) in the area of atomistic-based modelling of polymer composite degradation at Delft University of Technology in the Netherlands.

The successful applicant will work with Dr. Angelo Simone (Computational Mechanics of Materials Group) and Prof. Barend Thijsse (Virtual Materials and Mechanics Group) on a project funded by the Technology Foundation STW through the High Tech Materials program. The position is to commence in spring/summer 2015 or as soon as possible thereafter.

We've recently published an open access journal paper that looks at the mechanics of sutures used to repair severed tendons. A homogenization strategy is used to derive effective elastic properties for tendon fibrils and intracellular matrix. We have found that regions of high stress correlate with the regions of cell death (necrosis) that are sometimes observed in patients.

If this is of interest, please feel free to view the paper here.
