This joint Doctoral Scholarship project between Swansea University (UK) and Grenoble-Alpes University (France) will heavily focus on the experimental characterizations and constitutive modelling of biological soft tissues. The prime objective is to elaborate a large experimental database about some specific soft tissues as for example intestine, fascia or oesophagus which will facilitate to obtain important and pertinent experimentations about the viscoelastic behaviour of such tissues by performing very different tests (cyclic tests, relaxation test, influence of the strain rates, different tensile loading conditions, 
). Based on the experimental results, constitutive equations aim to represent the anisotropic and viscoelastic behaviour of soft tissues will be formulated. The anisotropy of the soft tissues are directly link to the presence of different fibres and to their orientation. Their orientation will be known by means of histological analysis. The viscoelastic properties will be deduced from experimental results and soft tissues physical parameters involved in the mechanical behavior will be demonstrated. All these parameters will be integrated in the representation of the orientation of the fibres in space and will be represented by an adapted probability density. The constitutive equations developed aim to be used to treat real life medical problems. Hence it is necessary to be able to simulate complex structures. In this regard, the developed constitutive model will be implemented in finite element software, e.g. Abaqus or Ansys. The implementation needs to find a complex mathematical problem considering derivations of the elasticity tensor and taking into account the penalisation due to the incompressibility of soft tissues.

For the project experimental works, student will stay in the Grenoble-Alpes University (France) while the computational modelling and validation works will be conducted in the World-leading Zienkiewicz Centre for Computational Engineering (ZCCE) in Swansea University.

Eligibility

Applicants must hold a Master's degree in Mechanical Engineering, Bio-medical Engineering, Computational Engineering or Mechanics to meet the entry requirements of both Universities.

Prior knowledge on experimentations of soft/polymeric materials is preferable.

We would normally expect the academic and English Language requirements to be met by point of application. For details on the University’s English Language entry requirements, please visit – http://www.swansea.ac.uk/admissions/englishlanguagerequirements/

Due to funding restrictions, this scholarship is open to UK/EU candidates only.

Benefits

This scholarship covers the full cost of UK/EU tuition fees and an annual stipend of ÂŁ14,777.

An additional ÂŁ500 per annum is provided each of the three years to assist with travel and accommodation costs.
