PhD position on multiscale analysis of polymer composites using multigrid method

EFFECT OF CORONA ON APPLICATION PROCESS

Job description

Polymer composites based on thermoplastics as well as elastomers are promising materials for the next generation industry, due to their unique mechanical properties, such as hyper elasticity, high stiffness to density ratio and low cost of manufacturing. Polymer composites generally have two phases, i.e. soft polymer matrix and stiff filler. The micro-scale interaction between fillers and matrix intrinsically determines the macro-scale mechanical behavior of polymer composites, while the macro-scale behavior of polymer composites significantly affects the status of micro-scale fillers. This cross-scale relationship is valuable to guide and optimize the applications of polymer composites, as well as to help the design and manufacturing of new polymer composites. However, multiscale analysis that can reveal the cross-scale relationship in polymer composites is challenging, due to high computation cost and difficulty of numerical implementation.

Objective
The multigrid method developed by Prof. C. H. Venner has great advantages, especially its high computational efficiency and accuracy, in simulating the mechanical response of heterogeneous materials consisting of different phases. It is adopted as the theoretical basis and will be further developed for multiscale analysis of polymer composites under thermomechanical loading conditions. The multiscale simulation will be able to concurrently capture the macro-scale thermomechanical behavior of polymer composites, the micro-scale behavior of fillers and matrix as well as the cross-scale interactions.

Your profile

  • You hold a master’s degree in Mechanical Engineering, Materials Engineering or equivalent;
  • You have experimental and/or theoretical skills in polymers or fiber reinforced polymer composites in the field of e.g. material characterization, analysis, manufacturing or mechanical performance.
  • You have an affinity with numerical modelling of the mechanical performance and experience with programming languages like Fortran or C++, scripting languages like Python or numerical computing environments like Matlab, ABAQUS and ANSYS.
  • You have a strong interest in continuum mechanics, combining dedicated experiments with lean and efficient numerical modelling;
  • Your writing skills are good and you have good experience in writing technical reports and/or scientific papers;
  • You have excellent analytical skills and critical mindset;
  • You are a team player with good interpersonal skills;
  • You are fluent in English, both spoken and written. (We require a TOEFL > 90 or IELTS > 6.5 score).

Our offer

We offer a very challenging multidisciplinary position in the groups of Production Technology, Elastomer Technology and Engineering, Engineering Fluid Dynamics in the Faculty of Engineering Technology at University of Twente.
