GECOMPL: Generalised Continuum Models and Plasticity |
Dr Stefanos Papanicolopulos
|
The GECOMPL project aims to enable wider adoption of generalised plasticity models in practical applications. More specifically, the project proposes a detailed study of the formulation of both existing and new elastoplastic constitutive laws in the framework of generalised continua, leading to a better understanding of the different possible constitutive models and providing both the necessary theoretical basis and the appropriate numerical tools needed to use generalised continuum models in describing elastoplastic behaviour.

Flow and sintering of non-spherical particles in additive manufacturing |
Dr. Jin Sun
|
The Edinburgh part of the project focues on the multi-physics modelling of particle dynamics and sintering behaviour in selective laser sintering processes. This work is an integrated part of an EPSRC funded project to develop fundamental understanding of particle behavour in additive manufacturing, collaborating with the University of Exeter. This project proposes to investigate the way polymeric powders of different shapes and sizes flow, interact and sinter in the laser sintering process, through modelling and experimental validation. Laser sintering is part of the additive manufacturing technology, known for its benefits in industries where custom made products, lightweight and complex designs are required.

FireComp: Modelling the thermo-mechanical behaviour of high pressure vessel in composite materials when exposed to fire conditions |
Dr Stephen Welch
|
Hydrogen is expected to be highly valuable energy carrier for the 21st century as it should participate in answering main societal and economical concerns. To exploit its benefits at large scale, further research and technological developments are required. In particular, the storage of hydrogen must be secured. Even if burst in service of pressure vessels in composite material is very unlikely, when exposed to a fire, they present safety challenges imposing to correctly size their means of protection.

Fire Safety of Modern Timber Infrastructure |
Dr Rory Hadden
|
Exposed structural timber elements within a compartment creates an additional fuel load which must be considered in design. This research focuses on quantifying this additional fuel load, and understanding conditions where after burnout of the compartment contents, the additional exposed timber may stop burning (auto-extinguish).

Finite element implementation and detailed comparison of generalised plasticity models |
Dr. Stefanos Papanicolopulos
|
The lack of an internal length scale parameter in classical continua leads to unrealistic numerical modelling of some phenomena related to the microstructure of the material such as size effect and strain localisation.

Efficient DEM simulation of large systems of non-spherical particles |
Dr. Kevin Hanley
|
To enlarge the scale of discrete element modelled particulate system from spherical to nonspherical; to increase the computational efficiency of simulating the nonspherical system; to provide more insights of particulate solid mechanics in engineering applications.

Effect of particle shape, size and particle friction in granular solid flow in railway ballast |
Prof. Xuecheng Bian
|
In the Chinese southeast coastal areas, most of the rail transit infrastructures are built on the soft soil. Infrastructures construction and operation including high speed railway or urban railway system require a good understanding of the behavior of the soft soil subject to the static and dynamic loading induced by the infrastructure.

Effect of particle shape, size and particle friction in granular solid flow in railway ballast |
Prof. Xuecheng Bian
|
The aim is to develop a new understanding of the micromechanics of railway trackbed subjected to dynamic loads induced by high speed trains. This should lead to safer design of high-speed railway systems which require less maintenance and, therefore, are more sustainable.
