PhD Studentship: 3-Directional Frictional Mechanical Metamaterials (3DFMMs)

Metamaterials have extraordinary properties and functionalities not typically found in conventional solids. Among metamaterials, 3DFMMs represent a groundbreaking innovation for systems requiring efficient energy dissipation or damping under multiaxial cyclic loading conditions, while maintaining a lightweight and structurally efficient profile. The advantages of 3DFMMs are in their scalability (ranging from micrometre to centimetre scales), material compatibility (metals, polymers, and even ceramics), and operational resilience in extreme environments (e.g., high/low temperatures).

Friction-based metamaterials experience high localized shear stress, leading to their rapid wear and reduced performance over time, particularly under cyclic loading conditions. In the case of 3DFMMs, energy dissipation primarily occurs through friction, but material deformations also contribute to multi-directional energy dissipation.

This project aims to develop a program for the design of 3DFMMs with predictable and tunable energy-dissipation capabilities. The proposed framework will incorporate a sliding Coulomb friction, wear resistance analysis, and a deformation mechanism, informed by insights from the crystal plasticity framework.

Entry requirements:

Essential Criteria: Applicants should have, or expect to achieve, at least a 2:1 Honours degree (or equivalent) in Mechanical, Material, or Computer Engineering. A solid background in your engineering discipline and a dedication to design and manufacturing. Ability to work independently, as part of a wider team, and with staff members. Strong communication and excellent interpersonal skills. Enthusiasm, passion, and interest in programming.

Funding information:

The Wolfson School of Mechanical, Electrical and Manufacturing Engineering is offering a PhD studentship to fund one of three advertised projects commencing July 2025. Projects starting with the advert reference ‘SA24’ will be competitively assessed.

The funding award is for 3.5 years and provides a tax-free stipend of £19,237 per annum plus tuition fees at the UK rate. The studentship also offers a £2,000 Research Training Support Grant. Due to funding restrictions, this studentship is only available to those eligible for UK fees.

English language requirements:

Applicants must meet the minimum English language requirements.

How to Apply:

Apply online via the above ‘Apply’ button. Under programme name, select ‘Mechanical and Manufacturing Engineering’ and quote the advert reference number ‘SA24-WS-AZ’ under the ‘Finance’ section of the application.

Applications must include a personal statement, up-to-date curriculum vitae (CV), details of two referees (one from your highest degree qualification), and certified academic certificates and transcripts for all completed degree programmes. Submission of a Research proposal is not essential but may strengthen your application.

Incomplete applications received after the advert closing date may not be considered for interview. Interviews are expected to be held in late April/May 2025. You will be contacted by the project supervisor if shortlisted for interview.

The School will use the selection criteria to help make a decision against your application.
