PhD Studentship - Corrosion-sensitive Multiscale Fatigue Modelling

Cranfield University

Start Date: Cranfield campus – 1th Oct

Duration of award: 3 years

Supervisors:

Dr. Gustavo M. Castelluccio
Professor Rajkumar Roy

Sponsored by EPSRC, this studentship will provide a bursary of up to £20,000 p.a. (tax free) plus fees* for three years

This PhD studentship will innovate on fatigue life predictions by explicitly taking into account corrosion-induced changes in composition at the crack tip. This work will employ 3D multiscale and multiphysics models to assess the potency for fatigue crack growth after corrosion degradation. A seamless integration with experiments will validate the response of the bulk material degraded by corrosion. This project is part of the Through-life Engineering Services Centre and the student will benefit from the industrial interactions and research collaborations.

The need for cost-efficient research that prevents fatigue failures has pushed towards integrated computational materials engineering approaches that improve competitiveness. These approaches rely on physics-based models that can be validated with experiments and bottom-up models at multiple scales in order to predict the macroscopic response. Hence, this research will investigate the degradation of metallic materials under corrosion-fatigue conditions by integrating multiscale physics-based models combined with mesoscale experimental tests.

The principal objective of this research is to predict the effects of corrosion-induced changes in composition on fatigue damage in metallic materials. We will employ 3-D crystal plasticity models in order to understand the role of compositional changes in fatigue damage. We will correlate these changes with a realistic degradation from corrosion processes. The simulations will be integrated with mesoscale experimental to evaluate the constitutive response of smooth specimens degraded by corrosion. Given the innovative nature of this research, it will represent a milestone in corrosion-fatigue research and will likely mark a path towards future degradation assessments.

Entry requirements:

Applicants should have a first or second class UK honours degree or equivalent in a related discipline, such as physics, material science and engineering. The ideal candidate should have some understanding in the area of solid mechanics modelling or experiments. The candidate should be self-motivated, have good communication skills for regular interaction with other stakeholders, with an interest for industrial research.

Funding:

* To be eligible for this funding, applicants must be a UK national.We require that applicants are under no restrictions regarding how long they can stay in the UK i.e. have no visa restrictions or applicant has “settled status” and has been “ordinarily resident” in the UK for 3 years prior to start of studies and has not been residing in the UK wholly or mainly for the purpose of full-time education. (This does not apply to UK or EU nationals). Due to funding restrictions all EU nationals are eligible to receive a fees-only award if they do not have “settled status” in the UK.
