PhD Position in Industrial Manufacturing Processes group: "Computational Assessment and Optimization of Metallic Additive Manufacturing Processes" (VAC-2021-29)

Published: 26/03/2021


Title of the PhD project:

Computational Assessment and Optimization of Metallic Additive Manufacturing Processes

Introduction:

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

Salary (gross): 17.563,14 EUR

Weekly working hours: Full time

Duration: 3 years

Starting date: No later than Sept 2021

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 Engineering Mechanics - 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 computational techniques for the numerical simulation and optimization of Additive Manufacturing processes.

The possibilities of Additive Manufacturing (AM) compared to conventional manufacturing are the cause of its great usefulness for designing new components and parts due to its flexibility and versatility. The performance of AM components is very much related to the manufacturing process optimization. Therefore, the numerical simulation and optimization of the AM process is the main goal of this proposal.

One of the main task of the PhD research is the development of a Reduced Order Model (ROM) of the melt-pool (both thermal and mechanical models) allowing for a great improvement of the computational time required for the thermo-mechanical analysis.

The prospective outcome of the thesis is to contribute in the development of the ROM-AM module within the in-house HPC software framework for the numerical simulation of AM processes.
