Summary of the impact

It is well-known that certain bridges are susceptible to potentially dangerous uncontrolled vibrations; recent examples include London's Millennium Bridge and the Volga Bridge in Volgograd. Correcting such problems after the construction of the bridge can be extremely expensive and time-consuming. Research in the Department of Mathematical Sciences at the University of Liverpool has led to a novel approach for predicting such behaviour in advance and then modifying the bridge design so as to avoid it. During the period 2011-12 this research has been incorporated into standard design procedures by industrial companies involved in bridge design. There is an economic impact for the companies concerned (avoiding costly repairs after bridge construction) and a societal impact (improvements in public safety and also avoiding the inconvenience of long-term closure of crucial transport links).

The research is based on a novel, highly non-trivial approach that has been developed to study properties of elastic waves in complex engineered structures with a multi-scale pattern. The work has been taken up by the industrial construction company ICOSTRADE S.R.L. Italy, whose design engineer Dr Gian Felice Giaccu integrated the innovative research ideas into their standard design procedures for complex structures such as multiply supported bridges. Novel designs of wave by- pass systems developed by the Liverpool group have also been embedded in standard algorithms by the industrial software company ENGINSOFT, in the framework of a project led by their project manager Mr. Giovanni Borzi.

The GRANIT system is a non-destructive technique for assessing the condition of rock bolts and ground anchors used to support structures such as tunnels. It applies a small impulse to the bolt and interprets the resulting vibration response to provide estimates of load and unbonded length. Initial development of the system was based on the findings of EPSRC projects in tunnels undertaken by the Universities of Aberdeen and Bradford from 1989-1997, resulting in an empirically based method. However, research undertaken at the University of Aberdeen since 1998 has provided the understanding of the process and developed the fundamental engineering science needed to underpin the development of a full commercial system. The GRANIT system is patented, and has been subject to worldwide licence to Halcrow who have undertaken testing and provided a method of ensuring the safety of mines, tunnels and similar structures. Halcrow received the NCE award for Technical Innovation Award for GRANIT in December 2010. The impact of the research has been in part economic, but largely on practitioners and professional services.

Summary of the impact

University of Bradford research has enabled a material manufacturing company, Armacell, to reuse up to 95% of its production waste to produce new, high-value acoustic products with up to 50% better acoustic performance than any competition products of similar size. We protected the developed IP through several international patents and set up a spin-off company, Acoutechs Ltd, to explore this technology commercially. These materials are now used to reduce noise levels below the recommended limits and to improve the general acoustic quality of spaces at home and work for the benefit of public health. The products generate an annual turnover of more than €4 million for Armacell and prevent more than 500 tonnes of plastic waste from going into landfill annually.

Summary of the impact

The Computational Mechanics and Reliability Group at the University of Greenwich has been developing computational methods for predicting material behaviour and component reliability since the late 1990s. This case study details economic and environmental impacts and impacts on practitioners. In particular it shows how our expertise has:

• substantially aided companies to predict reliability of new electronic systems before physical prototyping providing significant cost savings;
• enabled companies to assess impact of new materials that address environmental legislation;
• provided information to the Cutty Sark Trust in help maintain this national maritime treasure.

Summary of the impact

For aerospace vehicles, the development of new materials and structural configurations are key tools in the relentless drive to reduce weight and increase performance (in terms of, for example, speed and flight characteristics). The economic drivers are clear — it is widely recognised that it is worth approximately $10k to save one pound of weight in a spacecraft per launch and $500 per pound for an aircraft over its lifetime. The environmental drivers (ACARE 2050) are also clear — reduced aircraft weight leads to lower fuel burn and, in turn, to lower CO₂ and NO_x emissions. With such high cost-to-weight ratios, there is intense industrial interest in the development of new structural configurations/concepts and enhanced structural models that allow better use of existing or new materials. Analytical structural mechanics models of novel anisotropic structures, developed at the University's Advanced Composites Centre for Innovation and Science (ACCIS), are now used in the industrial design of aircraft and spacecraft. Based on this research, a new, unique anisotropic composite blade, designed to meet an Urgent Operational Requirement for the MoD, is now flying on AgustaWestland EH101 helicopters that are deployed in Theatre. In addition, the new modelling tools and techniques have been adopted by Airbus, AgustaWestland, Cassidian and NASA and incorporated into LUSAS's finite element analysis software. These tools have, for example, been used to inform Airbus's decision to use a largely aluminium wing design rather than a hybrid CFRP/aluminium wing for the A380.

Summary of the impact

As 288,000 UK construction workers were estimated to have contracted vibration white finger and 170,000 had claimed compensation by 2011 this study relates to the design and development of a hand and arm vibration (HAVmeter) monitor by the ERPE Reactec student start-up company. This company initially focussed on optimisation of sweeping for curlers, contributing to team GB winning the 2002 Winter Olympic Gold medal. The current Reactec (HAVmeter) instrument measures and reports on vibration white finger, which potentially affects 5 million British workers.

The HAVmeter has sales in excess of £9M, over the 2008-2013 period, and is now in use by 45,000 construction workers. Reactec, with 23 employees and a turnover of ~£2.5M p.a., company innovation has been recognised with 4 industrial awards since 2009.

Summary of the impact

Research at the University of Cambridge Department of Engineering (DoEng) has led to the creation of a method for measuring strain throughout a range of civil engineering structures using Distributed Fibre Optic Sensing (DFOS) and computing the stresses in these structures. This detailed information and associated insights have reduced reliance on conservative safety margins, while giving greater assurance of safety. The result has been significant reductions in construction materials and construction time. The work has generated direct savings of over GBP15M in three major infrastructure projects from 2011 to 2013 including Crossrail. It has had a wider influence across the whole industry by setting standards for geothermal piles in 2012, which were instrumental in the creation of this new industrial sector, and by changing attitudes in construction about the value of instrumentation and modelling.

Summary of the impact

The automotive and aerospace industries are keen to reduce their environmental impact and so have looked to move to lightweight materials. This creates issues in terms of joining, using and disposing of dissimilar materials. Oxford Brookes has therefore worked with national and multi-national companies in the adhesive, materials, automotive and aerospace industries to try to solve these problems. This has resulted in high quality research publications, innovative test equipment, improved numerical methods, novel designs, design guidelines, manufacturing procedures, British Standards, patents, commercial products and further funding. The impact of the work has global safety, environmental and economic benefits with multi-national aerospace and automotive companies implementing the results in current developments.

Summary of the impact

National and International design codes are the key vehicles for enabling structural engineering research to impact on practice. Recent years have seen substantial advancements in such codes for stainless steel structures, to which Imperial has made outstanding contributions [A-E]. Imperial research has led directly to improved structural design provisions, enabling more efficient structures, leading to cost savings [G], further promotion of the use of stainless steel in construction [A,H,I] and a reduction in the use of construction resources. The impact and reach of Imperial's research has not only been throughout the industry (producers [H], code writers [A] and practitioners [G,I]) but also global, with widespread influence on UK, European, North American and Asian practice [A].

Summary of the impact

Research at University of Cambridge Department of Engineering (DoEng) has created a new fundamental understanding of the static, dynamic and blast performance of lattice sandwich structures (a repeating pattern of metal struts between two sheets of metal). Ship builders in the Netherlands and the USA have built over 19 ships worth approximately GB200M using this technology since 1/1/2008 with many more planned. These ships are:

• less likely to rupture in low speed collisions, which is important especially for river tankers
• compliant with new standards for the carriage of dangerous goods by inland waterways in Europe at a lower cost, because the designs are simplified
• blast resistant, which is important when considering potential terrorist threats.
