Title The Art of Engineering 
Description From July 2013 Bob Levene was the Artist in Residence in the Faculty of Engineering, university of Sheffield. She observed the work that goes on in the Faculty (including our work on tennis surfaces), exploring into the everyday practices of the researchers and getting to grips with the tools, processes and machines that are used. 
Type Of Art Film/Video/Animation 
Year Produced 2014 
Impact She made a series of artworks based on the initial research, that were exhibited at Festival of the Mind 2014 in addition to other events and venues.

Description This project took a multidisciplinary approach to improving understanding of shoe-surface interaction, combining mechanical and biomechanical techniques. It aimed to improve the quality and safety of sports surfaces through an improved understanding of the factors associated with shoe-surface traction when performing on synthetic playing surfaces, with a specific focus on surfaces used in tennis. The level of traction between the shoe and surface is the most frequently cited factor influencing injury occurrence and player performance. For example, a high percentage of injuries requiring medical treatment have been attributed to uncontrolled slipping as a result of low traction. In addition, ankle inversion injuries and anterior cruciate ligament (ACL) tears have been associated with a high level of traction between the shoe and the surface.



This project addressed the problem of traction-related injuries in sport and exercise by considering the specific characteristics of shoes and surfaces that influence their translational and rotational traction behaviour under loads applied during sporting applications. To achieve this aim, a multidisciplinary approach was used. New mechanical test methods were developed to characterise playing surfaces, using biomechanical data to provide boundary conditions, the most useful being a bespoke lab-based traction rig capable of simulating shoe-surface interactions for a range of loading conditions. Engineering approaches have been used to determine specific material characteristics that influence the tribological mechanisms at play and consequent shoe traction behaviour. Human testing has been used to validate the results of mechanical tests and to investigate relationships between human biomechanics and perception and the material properties of tennis surfaces.
Exploitation Route There is potential for public engagement projects due to the accessible topic of tennis and sport. Some press releases have been put out leading to media coverage. Findings have been disseminated to the relevant academic audiences through journal papers and conference presentations (see Research Outcomes).



As well as improving understanding of the physical interaction between player-shoe combinations and sports surfaces, this work has the potential to lead to improving standard test procedures for sports surfaces, both integral to ensuring a high level of performance and comfort (to encourage participation), and reducing the likelihood of injury.



The International Tennis Federation (ITF) have organised a collaborative study hosted by the LTA to combine biomechanical kinetic and kinematic data with surface testing methods developed during this study. This has led to a new PhD project, sponsored by the ITF to develop a new portable court test device.



Further collaborations have also been fostered with the Health and Safety Laboratory, Buxton, to look at more general shoe-surface interactions and how they affect pedestrian movements (for instance an EPSRC proposal was developed for the Design for Wellbeing call - ageing and mobility in the built environment).



Proof-of concept projects have also been carried out in collaboration with safety shoe and flooring manufacturers and we hope to apply the proven methodologies into the general fields of pedestrian safety and human-floor interactions, with potential to study falls in older populations.

EPSRC Impact Acceleration funding has since been used to develop a device to assess slip resistance of footwear.
