<h2 class="heading hide-accessible">Summary</h2>

Granular materials refer to a class of natural and synthetic materials consisting of individual particles that interact with each other when subjected to loading. These materials behave differently from usual solids and exhibit many salient features such as dilatancy, anisotropy, pressure dependence, density dependence, and nonlinear elasticity.

<h2 class="heading hide-accessible">Full description</h2>

<p>The mechanical behaviour of granular materials is a subject of long-standing interest in many fields, with both scientific fascination and practical importance such as high value manufacturing, nano-technology, pharmaceuticals, geotechnics etc. The overall response of a granular materials is highly dependent on the packing patterns and interactions of the constituent particles which are, further, closely related to the characteristics of the particles. Based on recent advancements in the understanding of contact behaviour in granular materials, it is known that surface irregularities play significant roles in the transfer of energy and forces between particles and dictate macroscopic behaviours of such materials. The academic and industrial communities&nbsp;desperately need new models that can accommodate surface roughness in the calculations of forces and therefore predict the performance of granular matter. The University of Leeds is a pivotal place to tackle this ground breaking issue since it has two world class institutes of &ldquo;Tribology&rdquo; and &ldquo;Particle technology&rdquo; to get together the top expertise in surface roughness characterisation and contact modelling with particle flow and characterisation. This project will be a great opportunity for you&nbsp;to be involved in a joint project between these two institutes. The project will be a computational project utilising the state-of-the-art modelling capability at the institute of Functional Surfaces and the industrially used commercial model based on Discrete Element Method available in the School of Chemical and Process Engineering. There is an opportunity for you to collaborate with a number of academics and industries in a big consortium (<a href="https://mapp.ac.uk/">Manufacture using Advanced Powder Processes</a>)&nbsp;and also being part of a <a href="https://www.it-cdt.co.uk/">Centre for Doctoral Training in Integrated Tribology</a>. You&nbsp;will also be part of the world-leading Institute of Functional Surfaces working along with about 70 PhD students and 25 PDRAs to facilitate the dissemination of the project.</p>

<h2 class="heading">How to apply</h2>

<p>Formal applications for research degree study should be made online through the&nbsp;<a href="https://eps.leeds.ac.uk/mechanical-engineering-research-degrees/doc/apply">University&rsquo;s website</a>. Please state clearly in the research information section&nbsp;that the research degree you wish to be considered for is &ldquo;Numerical simulation of contact behaviours of granular matters with heterogeneous surfaces&rdquo; as well as <a href="https://eps.leeds.ac.uk/mechanical-engineering/staff/616/dr-ali-ghanbarzadeh">Dr Ali Ghanbarzadeh</a>&nbsp;as your proposed supervisor.</p> <p>If English is not your first language, you must provide evidence that you meet the University&#39;s minimum English language requirements (below).</p> <p><em>We welcome applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates. All scholarships will be awarded on the basis of merit.</em></p>

<h2 class="heading heading--sm">Entry requirements</h2>

Applicants to research degree programmes should normally have at least a first class or an upper second class British Bachelors Honours degree (or equivalent) in an appropriate discipline.

<h2 class="heading heading--sm">English language requirements</h2>

The minimum English language entry requirement for research postgraduate research study is an IELTS of 6.0 overall with at least 5.5 in each component (reading, writing, listening and speaking) or equivalent. The test must be dated within two years of the start date of the course in order to be valid.

<h2 class="heading">Funding on offer</h2>

<p><strong>UK/EU</strong> &ndash; Engineering &amp; Physical Sciences Research Council Studentships paying academic fees&nbsp;(&pound;4,600 for Session 2020/21), together with a maintenance grant paid at standard Research Council rates (&pound;15,285 for Session 2020/21) for 3.5 years. UK applicants will be eligible for a full award paying tuition fees and maintenance. European Union applicants will be eligible for an award paying tuition fees only, except in exceptional circumstances, or where residency has been established for more than 3 years prior to the start of the course. Funding is awarded on a competitive basis.</p>
