Project Description

Objectives

Recent results have proved that PF approaches can quantitatively predict crack nucleation for mode-I loading. However, current models do not allow for a faithful prediction of the crack nucleation event in more complex loading conditions and materials.

A further important limitation of PF models is their difficulty in reproducing fracture propagation under compressive loadings, despite the important amount of work on the subject. The principal aim of the ESR-5 project will be to investigate crack nucleation and propagation under compressive loadings and to propose novel extension of the PF approach to overcome the current limitations.

The project will include theoretical and numerical developments. The new methodologies for PF applied to fracture in compression will imply the development of coupled damage-plasticity and multi-field models. The numerical procedures, based on the FEniCS framework, will be released into the NEWFRAC collaborative computational platform to benefit other ESRs. These procedures will be applied to compressive crack onset and propagation in LFRP laminates in aeronautical applications, layered ceramics with residual compressions, and bones.

Additional Information

Benefits

A full-time fixed-term contract is offered. Marie Curie ITNs provide competitive financial support to the ESR including: a competitive monthly living and mobility allowance and salary, coverage of the expenses related to the participation of the ESR in research and training activities (contribution to research-related costs, meetings, conference attendance, training actions, etc.). The recruited researchers will have a regular contract with the same rights and obligations as any other staff member of the institution.


Eligibility criteria

Applicants must at the time of recruitment:

  1. Be in the first four years (full-time equivalent) of their research careers. The four years start to count from the date when a researcher obtained the degree (e.g. Master’s degree) which would formally entitle him/her to embark on a doctorate.
  2. Candidates could be of any nationality but have not resided in the host country for more than 12 months in the last 3 years.
  3. Have not been awarded a doctoral degree.

Selection process

Applicants are evaluated by a selection committee on the basis of past academic performance (grades) and background, scientific relevance and aptitude to research, and any other additional pertinent data submitted in the application (such as scientific publications, if any).

The candidates that pass the initial assessment of the applications will be invited for an interview with the selection committee, either in person at the campus, or via standard internet videoconference. Equal opportunities are ensured to all candidates throughout the evaluation process.
