Title of the PhD project:

Non-linear numerical analysis of composite beam structures using a multiscale method based on domain decomposition


The International Centre for Numerical Methods in Engineering (CIMNE) is a research centre, created in 1987 by consortium between the Catalan Government and the Universitat Politècnica de Catalunya (UPC-BarcelonaTech), devoted to the development and application of numerical methods to a wide range of areas in engineering. CIMNE has been selected as a Severo Ochoa Centre of Excellence for the period 2019-2023. This is the highest level of recognition of excellence and leadership awarded to a research centre in Spain.

Position details:

Number of vacancies: 1

Category: PhD (PHD2)

Workplace: Barcelona

Functions to be developed by the applicant:

CIMNE is looking for a PhD Researcher to be part of the Research and Technical Development (RTD) Group on Structural Mechanics. The functions assigned to the candidate will be:

  • Complete a PhD on Structural Analysis doctoral program at Universitat Politècnica de Catalunya – Barcelona Tech. The candidate is expected to complete the PhD thesis in a maximum of three years.
  • Collaborate with various research groups within CIMNE and worldwide.
  • To publish a minimum of two papers in JCR journals during the PhD period, author and co-author articles in high-impact international journals.
  • Carry out quality research, training and management.
  • Participate on the dissemination and outreach activities associated with the project.
  • Participate in international conferences presenting her/his work.
Description of the PhD Project:

Classic beam theories are insufficient for the analysis of beams with a complex material micro-structure, such as composites, or with a complex geometric configuration. In order to minimize the numerical cost of these analysis, maintaining an optimal accuracy in the solution, this work will use the formulation developed by J.A. Hernandez [1] in which the beams are solved using a multiscale method using a domain decomposition and ECM-hyperreduction models. This formulation will be extended to the non-linear range and applied to the solution of composite structures. In order to increase the capabilities of the formulation to solve large structures, it will be implemented in Femuss finite element code, which will allow to solve i.e. structural problems interacting with fluids.

The models developed will be applied to analyse curved pultruded profiles [2], which will be manufactured and tested in the framework of Fibre4yards EU project [3].
