Fully-funded PhD position in Computational Mechanics

PhD project 2 (Reference: NGCM-0080)Design and optimisation of bio-inspired programmable surfaces with active materialsBiotribology Group, nCATS
Faculty of Engineering and the Environment
University of Southampton, United KingdomBackgroundIn Nature, a number of animals and plants have evolved the ability to exploit patterned surfaces at various scales (e.g. Lotus flower, shark cuticles) to their advantages. Dynamic or adaptive patterned surfaces are very desirable as they can be adapted to specific contexts, operating conditions and environments.Cephalopods such as octopus, squid and cuttlefish possess some of the most striking abilities in the animal kingdom: camouflage via rapid colour change and, of particular relevance for this project, adaptive change of the three-dimensional texture of their skin. Their skin acts as a programmable morphing soft surface.In an engineering context, this type of functional ability can open up a vast array of practical applications from programmable haptic surfaces, morphing skin to control hydro-/aerodynamic drag (i.e. tunable friction) through antibiofouling strategies, to flexible electronics and tissue engineering and regenerative medicine.The projectIn this research, it is proposed to explore the use of soft active materials that respond to external stimuli in a controlled manner to induce various levels of potentially large surface deformation. Soft active materials respond to an external stimulus to perform a function or exhibit a change in material properties. Examples include dielectric elastomers that deform under electricity and force, and hydrogels that swell under a change in temperature or pH value.The proposed research aims to understand the physical mechanisms behind surface instabilities and to achieve enhanced functions by harnessing or suppressing instabilities through the development of a robust and efficient finite element environment featuring integrated optimisation techniques. We aim to model how coupled fields such as stress, electric field, and chemical potential interact together to cause deformation and instabilities in such materials.Theoretical modelling and numerical simulations will be performed to better understand such coupled responses. It is anticipated that the numerical tools to be developed may advance the understanding of surface patterning, and also facilitate the design of new materials and structures.General informationThe position is open to EU students only but exceptional overseas students could be considered.The successful candidate will work in a stimulating research environment, supported by world-leading organisations such as Procter & Gamble, Rolls Royce and the US Air Force and will be encouraged to work with our international academic and industrial collaborators in Europe, South Africa, New Zealand, Singapore and the USA.If you wish to discuss any details of the project informally, please contact Prof. Georges Limbert, nCATS and Bioengineering research group, Email: g.limbert@soton.ac.uk, Tel: +44 (0) 2380 592381.This project is run through participation in the EPSRC Centre for Doctoral Training in Next Generation Computational Modelling (http://ngcm.soton.ac.uk).

PhD at Arts et Métiers ParisTech. Phase field modeling of damage and fracture in polycrystalline materials

A PhD research subject is proposed for students to apply at Arts et Métiers ParisTech.The ability of scientists and engineers to exploit, design and process new materials with improved properties has often been fundamental for the technological advances of societies. In fact, advances in many key domains like aerospace, automotive industry, energy, nanotechnology, rely on our ability to engineer new materials and exploit their properties. For metallic materials, such technological advances usually requires a deep understanding of how mechanical and physical properties are influenced by microstructural features (e.g. grain size, crystallographic orientation). The investigation of the relation between macroscopic properties and microstructure is however a complex task. Indeed, under service conditions or during processing, microstructural transformations are observed and the associated properties may significantly change depending on the loading conditions. An optimal exploitation of engineering alloys therefore requires the development of microstructure sensitive constitutive models, which explicitly account for the influence of microstructural heterogeneities on the mechanical behavior.In the present work, we are interested in the development of a model which is dedicated to the description of damage in polycrystalline metallic materials. Indeed, the progressive degradation of mechanical properties for such materials is an important issue in many engineering situations (e.g. fatigue design, creep design). This study thus aims at building a model that would describe how cracks initiate, propagate and interact with each other at the micro-scale.To reach this objective, it is proposed to use the phase field method (PFM) within the context of polycrystalline plasticity. Indeed, within the framework of irreversible thermodynamics, the phase-field method has proved to be extremely powerful in the description of microstructural transformations without having to track the evolution of individual interfaces, as in the case of sharp interface models. In the present case, it is expected that the introduction of an order parameter associated with damage will allow capturing some complex phenomena like crack kinking or crack branching. The proposed study would therefore consists of:
(1) Defining an appropriate set of internal variables (and the associated energy potential) to deal with both elasticity, plasticity and damage in crystalline materials at the microscale
(2) Deriving the evolution equations associated with the different internal variables within the context of the phase field method
(3) Implementing the constitutive equations within an appropriate numerical solver (finite element solver for instance)
(4) Validating the proposed formulation by testing its ability to reproduce some known experimental results.At the end of this PhD research program, the numerical model will allow for investigating the interactions between various physical mechanisms governing the macroscopic behavior (e.g. plasticity, damage) at different length scales. Also, since the proposed model will offer a more accurate description of the mechanical behavior of metallic materials, it will help in optimizing the design structural components.http://www.adum.fr/as/ed/voirproposition.pl?langue=fr&site=ensam&matricu...

PhD Studentship in Cyclic Plasticity of Additively Manufactured (AM) Metals

PhD Studentship (4 years) @University of Limerick
Cyclic Plasticity of Additively Manufactured (AM) Metals: Experimental Investigation & Constitutive ModellingBackground & Research ObjectivesTo date, most of the published research work on the mechanical properties of additively manufactured (AM) metals has been on the observed monotonic and fatigue performance. Very limited attention has been placed on the cyclic elastoplastic response of this class of metals, despite the significance of this area for many aerospace and mechanical engineering applications. Further investigation in this area can assist in characterising the AM metals’ macroscopic mechanical behaviour (e.g. stress and strain hardening), as well as assess the influence of microscopic characteristics (microstructure) and manufacturing parameters (e.g. built orientation) on their mechanical behaviour, including low and high cycle fatigue.This 4 year research project will investigate experimentally the elastoplastic behaviour of metallic materials produced via commonly used AM methods (e.g. selective laser sintering, selective laser melting), under cyclic loading, in the ultra-low, low and high cycle fatigue regime. The study will cover an array of different materials, loading cases and histories, both in the uniaxial and multiaxial stress space. Moreover, the experimental results obtained will be utilised to develop and validate constitutive plasticity models capable to predict the cyclic elastoplastic behaviour and performance of the various AM metals, under ultra-low, low and high cycle fatigue loading.Studentship Terms and Conditions
