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 Industrial Manufacturing Processes.

The functions assigned to the candidate will be:

  • Complete a PhD on Structural Analysis 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 three 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:

This project aims to the development of concrete AM technologies, namely D-shape and Contour-crafting, suitable for building and construction.

D-shape is a novel powder-bed technique for Additive Manufacturing (AM) using cement-based materials and polymeric fibres which has proved to be a promising construction technology, still under development.  D-Shape is a method of digital construction making use of a binder jetting 3D printer for civil and architectural applications. D-Shape materializes building or architectural components directly from the CAD design by spreading a sequence of layers of granular material. A selective binder jetting allows for turning the granular material into the expected shape.

Contour Crafting (CC) additive manufacturing (AM) technology uses specially designed robotic systems to build self-resistant structural components (capable of resisting their own weight at fresh state) making use of data from 3D computer-aided design (CAD) systems. This AM system allows minimizing construction times and the avoidance of formworks and labour-force, while reducing the cross-section material consumption and guaranteeing sustainable (economic, environmental and social) solutions versus those traditionally used in building and construction.

This goal will be achieved by means of the following prospective outcomes:

  • Development of a D-Shape AM-design framework for: a) the numerical analysis and simulation of the D-shape AM construction process, and b) the analysis of the built structure under in-service operations. The software platform will be able to reproduce the whole construction process and to predict and monitor the performance of 3D-printed structures computing the mechanical properties (stiffness and strength) during the whole duration of the D-shape process and at any point of the built structure. It will also useful for optimizing the amount of material needed for the construction process, as well as for predicting the behaviour of the D-Shape AM structure under service load conditions.
  • Development of a CC/AM-design framework for the numerical simulation of the CC/AM construction process and the in-service operations. The CC/AM software platform will reproduce the AM construction process and will also predict and monitor the performance of the AM structures, computing the mechanical properties (stiffness and strength) during the duration of the CC/AM process at any point of the built structure.
