PHD VACANCY ON REDUCED ORDER METHODS FOR DAMAGE MODELLING IN COMPOSITES

(ref. BAP-2018-303)
 

The KU Leuven Noise and Vibration Research Group is headed by Prof. Wim Desmet (www.kuleuven.be/wieiswie/en/person/00011973) and currently counts 8 permanent staff members, 16 senior post-doc and 55 PhD researchers. The group has a longstanding history and internationally highly recognized expertise in the fields of engineering dynamics of (mecha(tro)nic) systems, vibro-acoustic modelling, simulation, analysis and testing, identification and control of (non-)linear systems, and lightweight structure design and analysis. The Noise and Vibration research group is also recognized for its yearly Acoustics (ISAAC) and Modal Analysis (ISMA) courses and for organizing the biennial ISMA Noise and Vibration Engineering Conference (www.isma-isaac.be).

Project

The aim of this project is to develop robust Reduced Order Methods (ROM) that can be applied to damage modelling in composites at the micro- and meso-scale. This project is a 4-year research project (funded by SIM Flanders) where the research group UGent-MMS at Ghent University (Belgium) will collaborate with the research groups KUL-PMA and KUL-MTM at KULeuven (Belgium). The Industrial Advisory Board consists of Siemens Industry Software (SISW), Honda R&D, Materialise, LCV and TWE Meulebeke. This published PhD position is a joint PhD position between UGent-MMS and KULeuven-PMA, which will require an intensive collaboration and commuting between the two research groups. UGent-MMS will provide the know-how on damage modelling in composites, and KUL-PMA the know-how and background on Reduced Order Methods (ROM).

In previous and ongoing research, UGent-MMS is developing material models for fibre-reinforced composites under static, impact and fatigue loading. Those models are applied to Representative Volume Elements (RVE) at micro-scale (for unidirectional composites) and at meso-scale (for textile composites). The first step at micro- and meso-scale is homogenization of the elastic properties. This is straightforward at micro-scale, but not at meso-scale. If a nested textile composite is modelled with a fine mesh and periodic boundary conditions, this simple linear elastic step can already take several hours of calculation time. When damage models are applied, the calculation times are exponentially increasing, even at micro-scale. The combination of nonlinearvisco-plasticity/damage modelling in the polymer matrix and fibre/matrixinterface debonding quickly leads to long calculation times. 

The main aim of this PhD is to investigate to what extent Reduced Order Methods can reduce the calculation times. In a first step, existing ROM will be applied to linear elastic cases and damage modelling. In a next step, dedicated new ROM will be developed. The PhD student will be assisted by two postdoctoral research fellows, respectively at UGent-MMS and KULeuven-PMA.

Profile

The PhD project is focused on reduced order modeling of composites. An ideal candidate has an M.Sc. in engineering and has a solid background in mathematics and preferably some knowledge about composites modeling.

  • We are looking for a candidate who enjoys working in the field of numerical modelling, who is curious and has the courage to try out new things.
  • Candidates have to be flexible in working both at the UGent-MMS site and at the KU Leuven-PMA site.
  • All candidates must be fluent in spoken and written English.
  • All members of the network are equal opportunity employers, both female and male candidates are invited to apply.
  • The applicant may be of any nationality.
Offer

KU Leuven in cooperation with UGent offers to the selected candidate a stimulating and ambitious research environment [1] which is embedded in the DNA of the region of Leuven, a premier destination for Health, High-Tech and Creativity [2] and considered an extremely nice place to live and work.

To assist Fellows in matters of work permits, visas, living, mobility, housing,… , KU Leuven has the International Admissions Office (an Official Marie Curie mobility centre recognized by the Flemish government) with dedicated Officers which offers new colleagues HR, Recruitment and Career Management support [3].
