I am Reader in Computational Mechanics at the Department of Mechanical and Aerospace Engineering of 91影视University London, which I joined in 2006 as a lecturer. Between 2001 and 2006, I was a lecturer in 'Scienza delle Costruzioni' (i.e. Mechanics of Solids and Structures) at the University of University of Naples ‘Federico II’. The latter is also my Alma Mater, where I obtained my 5-year degree in Civil Engineering in 1994 and my PhD in Structural Engineering in 1997. Between 1998 and 2001, I was a Post-Doctoral Researcher at the Department of Aeronautics of Imperial College London. In my research I am interested in modelling the behaviour of materials, solids and structures within and, more often, beyond their elastic limit, combining experimental methods with nonlinear numerical modelling. You can find more details here. The mechanics of solids and structures and its numerical modelling via linear and nonlinear finite element analysis are also the subjects of my teaching at both undergraduate and postgraduate level. Current interests include: Damage mechanics, fracture mechanics and cohesive-zone models, accounting for friction, plasticity, visco-elasticity, visco-plasticity and fatigue Rate-dependent failure of adhesive joints Composite delamination Nonlinear geomechanics Nonlinear modelling of concrete and reinforced concrete Multi-scale analysis of materials and structures Past interests include: Multi-scale numerical analysis of flexible risers Plastic buckling of metal structures Numerical and experimental analysis of lined pipes I am interested in modelling the behaviour of materials, solids and structures within and, more often, beyond their elastic limit, combining experimental methods with nonlinear numerical modelling. The latter include but is not limited to the development of nonlinear finite-element analysis. The applications have been quite wide-ranging and included the study of plasticity in metals, nonlinear behaviour of concrete and reinforced concrete, buckling of metal structures, composite delamination, debonding of adhesive joints, multi-scale analysis of flexible risers among others. On the other hand, the recurrent theme of my work is the application of fundamental principles and methods to study elastic and inelastic behaviour of solids and structures within a rigorous thermodynamic framework, accounting directly or indirectly for their behaviour and their hierarchical architecture at different scales. In the first decade or so of my research career, I was normally trying to answer the following type of research question: what is the the best way to find the solution of (well-posed) mathematical models that had already been developed by other researchers? At some point though, I realised that I am much more interested in this other type of question: what is the best mathematical model for a given problem? The latter requires interaction with the real world, understanding of the underlying physics, experimental testing and validation. Nevertheless, the former question cannot be avoided, because in order to test and validate a mathematical model one needs to make sure that the model is well posed and a solution can be found. This can be quite challenging and, like many other aspects of my research, it often requires a great amount collaboration with other colleagues. One area where I gained a certain recognition is the development of cohesive-zone models, which are a method to study crack formation and growth in solid or along structural interfaces. I started working in this field as a Post-Doctoral Researcher at Imperial College, studying the analysis of delamination of laminated composites under the supervision of late Prof. Mike Crisfield. I started using an existing model, developed by Prof Crisfield and his previous co-workers, which I only slightly modified and recast in the framework of damage mechanics. My main initial challenge was to get the implicit incremental solution procedure to converge. Since then, together with several collaborators I have developed other cohesive models that accounted for elasticity, damage, plasticity, viscoelasticity, viscoplasticity, friction, dilatancy and fatigue. My more recent interests include revisiting the methods of fracture mechanics applied to the case of ductile materials and nonlinear modelling of geomechanics problems.

Dr Kevin Hughes graduated from Cranfield University where he obtained an MSc in Astronautics and Space Engineering, prior to achieving his PhD in improving helicopter crashworthiness for impacts on water. Kevin has extensive experience in teaching (including development and delivery of new modules) at MSc / Continued Professional Development level, Operating as an MSc Course Director since 2005, Kevin achieved Senior Fellow status with the Higher Education Academy and has supervised over one hundred MSc industry supported dissertation projects to completion. Kevin's research interests are focused on the development of numerical simulation methods for non-linear structural analysis (including crashworthiness), which includes coupling finite element analysis to optimisation methods. Utilising high fidelity modelling of structures and materials has led to research colloborations within automotive, aerospace and rail sectors. Kevin’s research started with improving the level of crashworthiness for helicopters impacting onto hard and water surfaces through his PhD, which led to his interest in applying non-linear transient numerical simulation methods (mesh based and mesh free) to understand the response of structures and materials to a range of dynamic loading. Applications include the use of optimisation approaches to develop robust design solutions (by taking into account sources of uncertainty) for industrially sponsored research / EU collaborative projects. This led to Kevin’s involvement with a number of companies with challenging engineering problems, including Jaguar Landrover and Aston Martin related to car crashworthiness, failure assessment for Network Rail and led to a product to market by developing protection concepts for electronic devices in conjunction with Logitech (resulting in a US Patent).
