Speaker: Dr Colin Caprani, Monash University, Australia
Topic: Traffic Loading & Bridge Management
Venue: Harrison 171 (changed from Harrison 203)
Synopsis: In this talk I will proceed from a consideration of societal and structural engineering risks to show the role that the modelling of highway bridge traffic loading has in the management of existing bridges. This talk covers disciplines of structural reliability, structural dynamics and traffic engineering and so should be of interest across traditional discipline lines.
Biography: Dr Colin Caprani is the Director of Teaching and a senior lecturer in Department of Civil Engineering of Monash University, Australia. He is a Chartered Professional Engineer (CPEng MIEAust) and Chartered Structural Engineer (CEng MIEI, MIStructE) with considerable industrial and academic experience. He has worked as a design structural engineer on a wide range of projects, including integral bridges, new-concept bridge beam development, large-scale commercial mixed-use developments, and renovation and refurbishment of listed structures. His research specializations involve highway bridge traffic loading for short- and long-span bridges; vibration serviceability of footbridges; structural reliability and statistics of extremes; and Intelligent Transportation System – infrastructure interaction. He has lectured on numerous courses in three universities.
Date and time: Wednesday 7 November 2018, 13.30 - 14.15 including a question and answer session, followed by further discussion in the same room 15.30.
Speaker: Prof. Gavin Tabor, University of Exeter
Topic: Computational Fluid Dynamics: an Exeter Perspective
Venue: Harrison 170
Synopsis: Computational Fluid Dynamics is the solution of fluid dynamics problems using computers, typically in 2 or 3 spatial dimensions. Its use in engineering has grown inexorably over the last 20 years, fueled by the constant growth of computing power, and practically every engineering discipline has been impacted by the ability to perform predictive physics-based simulations of everything from heat transfer, combustion and reaction to multiphase and free surface flow.
In this seminar I intend to provide a personal viewpoint of the state of the art, and review four main aspects of the work from my group; OpenFOAM, research with the company Hydro International, scour and sedimentation, and optimisation through machine learning-driven CFD.
Biography: Prof Gavin Tabor joined the University of Exeter in 1999 after 5 years at Imperial College as a PDRA. Whilst at Imperial he was part of the informal team developing the FOAM code, now released as OpenFOAM; this has formed the core of his research programme here in Exeter, building a research team currently numbering 10 researchers and drawing on both industrial and EPSRC funding. During his 25 years experience in CFD he has worked on a range of techniques and areas including turbulence modelling, multiphase flow and combustion, and application areas including biomedical, SUDS, renewable energy, additive manufacture and optimisation.
Date and time: Wednesday 5 December 2018, 12.30 - 13.15
Speaker: Prof. James Brownjohn, University of Exeter
Topic: Structural condition assessment and performance of rock lighthouses around the British Isles
Venue: Harrison 170
Synopsis: EPSRC funded project STORMLAMP started in 2016 with modal (vibration) tests on a set of seven remote masonry towers perched on rocky outcrops around the British Isles. The project operates with very good teamwork between Plymouth (led by Alison Raby, experimental hydrodynamics and CFD), UCL (led by Dina D'Ayala, numerical structural modelling) and Exeter (led by myself, field testing and monitoring) with very strong technical and research support. While it's been a fun and photogenic project there have been several technical and logistical challenges and some interesting research outcomes. We've established the extreme high quality and robustness of the 19th century construction and the different behaviour of the 20th steel helidecks. We've worked out what lighthouse keepers meant when they said the structures seemed to rock during storms and we are getting a feel of the level of wave loads that cause this behaviour. The project has other benefits e.g. in terms of system identification uncertainty due to axisymmetry, and methods of characterising breaking wave loads on marine coastal structures.
Biography: James joined the University of Exeter as part of the Vibration Engineering Section in 2013. He has BSc in mechanical engineering (Bristol) and PhD in earthquake engineering (Bristol). After a few years with MoD, offshore oil/gas and coding he began an academic career in Bristol, then Singapore (where he learnt what fun you can have doing consulting work), then Plymouth, then Sheffield, then wound up in Exeter.
Date and time: Wednesday 16 January 2019, 13.30 - 14.15
Speaker: Prof. Prakash Kripakaran,University of Exeter
Topic: Flood resilience of bridge structures: Scour and hydrodynamic forces due to debris blockage
Venue: Harrison 170
Abstract: The talk will present research undertaken as part of the EPSRC-funded project - “Risk assessment of masonry bridges: Hydrodynamic impacts of debris blockage and scour”. Debris, which can worsen scour and increase hydrodynamic forces, is a leading cause of bridge failure in the UK and internationally. This project has characterized the scour and hydrodynamic effects of debris blockage through a combination of laboratory experiments and numerical (CFD) modelling. Results indicate that debris can amplify scour by a factor of 3, and highlight particularly the importance of paying attention to debris-induced scour in low flow conditions when bridges are often considered to be not at risk. The approach developed for assessing scour risk is in the process of becoming embedded within current guidance for practitioners, and is also being used by an industry partner via a secondment.
Biography: Prakash Kripakaran is a senior lecturer in structural engineering and academic lead for the civil and structures research group. He has an undergraduate degree from the Indian Institute of Technology, Madras, and a MS and PhD from North Carolina State University. Prior to joining Exeter in 2010, he worked as a postdoctoral researcher at EPFL in Switzerland. His research interests are mainly in the use of innovative sensing and computing techniques for maintenance and management of bridges.
Date and time: Wednesday 6 February 2019, 13.30 - 14.15
Speaker: Prof. Anthony Halog, University of Queensland
Topic: Understanding Interconnections and Pathways for Transitioning towards Circular & Low Carbon Economy via Systems Thinking
Abstract: Population and economic growth will result to an increase of approximately 40 percent in the demand for food, water, energy and other resources in the coming decades. To fulfil this demand in sustainable and efficient manner, while avoiding food and water scarcity, and environmental catastrophes in the future, some industries, particularly those in agri-food and energy production, have to drastically change its current production systems towards circular, low carbon, and green economy. In Australia, the food supply chains are economically and technologically developed, but have been facing enduring challenges on its international competitiveness and environmental burdens from its production processes. An integrated framework for sustainability assessment is needed to precisely identify inefficiencies and environmental impacts created during food production processes while respecting human-economic constraints.
This presentation proposes a combination of industrial ecology and systems science based methods and tools to develop a novel and useful methodological framework for life cycle sustainability assessment in agri-food industry. The presentation highlights circular economy paradigm aiming to implement sustainable processes to transform the prevalent linear-based model of agri- food supply chains. The framework will aid future Life Cycle and Integrated Sustainability Analysis, Social Life Cycle Assessment and eco-redesign of food and other industrial systems.
Bio: Anthony Halog holds a Ph.D. in Engineering Economics from Karlsruhe Institute of Technology, Germany and has been officially certified as an environmental Life Cycle Assessment (LCA) Practitioner by the American Centre for Life Cycle Assessment (ACLCA). His research focuses on the sustainability of human-nature complexity through understanding the nexus of material and energy systems. He leads the Research Group for Industrial Ecology and Circular Economy at the University of Queensland, which endeavours to provide service/expertise for industry clients (e.g. agri-food-energy systems) in transforming existing linear system-based value chains and operations towards circularity to enhance their resource efficiency & productivity and create added value products from wastes. He was previously an Assistant Professor in Industrial Ecology at the University of Maine (2008-2012), and an Assistant Professor in Operations and Technology Management in the School of Business at Brock University, Canada (2006-2008).

Speaker: Dr Tim Dodwell, University of Exeter
Abstract: I will talk about my recent working developing high performance scalable solvers for challenging models arising in composite materials and subsurface flow applications. The resulting equations of such models, cause significant numerical challenges, because the presence of multiple scales of uncertain and high contrast anisotropic material properties. The software I have development is an initiative to overcome the limitations of commercially available solvers by encapsulating the mathematical complexities of the underlying solvers within an efficient C++ framework, making the techniques more accessible to the broader scientific and industrial communities. The key innovation is the design and implementation of a robust, scalable parallel iterative solver. I will demonstrate the scalability of our solver over 15,000 cores on the national supercomputer Archer, by solving an industry problem in aerospace composities (for GKN Aerospace) with over 200 million degrees of freedom in minutes.
I will spend a good part of the talk, talking about current and future avenues of research in this area through collaborations with Rob Scheichl (Heidelberg), Mark Girolami (Cambridge/Turing) and Youseff Marzouk (MIT). This will include the interesting connections between the robust parallel iterative solvers developed and novel multiscale methods; and the exploitation of these solvers/methods for challenging Bayesian Inverse problems using a Multilevel Markov Chain Monte Carlo Methods I have developed with Scheichl.
