Brunel University London is a world class university that addresses the challenges facing society through ground-breaking research and educational programmes. Our mission is to combine academic rigour with the practical, entrepreneurial and imaginative approach pioneered by our namesake, Isambard Kingdom Brunel. With the fifth largest Engineering school in the UK, Brunel is ranked 83rd in the world for Engineering and Technology and 10th in the UK, with research articles published by Brunel attracting the highest citation score (90.5/100) of all UK institutions [THE World University Ranking 2013-14 published in October 2013]. Brunel currently holds an EPSRC portfolio of almost £45 million and in May 2014 was invited to become an EPSRC strategic partner.

Brunel University London is a public research university located in Uxbridge, London, United Kingdom. Founded in 1966, it was named after the Victorian engineer Isambard Kingdom Brunel. Brunel’s campus is located on the outskirts of Uxbridge

Research activities of primary relevance to EXTREME are within the Structural Integrity Theme. Structural Integrity (SI) can be defined as the science and engineering relating to the safe and reliable life/life cycle of structures. The field of structural integrity is primarily driven by social demands for safety, reliability, reduction of impact on the environment and greater economic efficiency in terms of total life cycle cost. This crucial engineering area, of relevance to industry, public services and the public at large, is of particular importance to key sectors such as aerospace & automotive, transport, construction, oil and gas and alternative energy.
Research into structural integrity provides the data, models and tools necessary for performing statistically reliable life prediction. Our structural integrity research focuses on design of new and assessment of existing real world materials and structures characterised by design, manufacture and maintenance imperfections. This includes:

  • Dynamic response and failure of materials;
  • Fatigue and other structural damage mechanisms, including variations in residual strength;
  • Ultrasound and acoustic emission methods for detection and characterisation of cracks and flaws;
  • Static and dynamic response of structures (metallic, composite and hybrid) including joints, isolated elements and also whole structural systems; and
  • Behaviour of structures under both normal and extreme loading conditions (e.g. exposure to elevated temperatures, very cold conditions, marine environments, etc.)
  • Manufacturing effects (e.g. geometric and material imperfections, residual stresses, etc.).

These research areas are the focus of our experimental and modelling activities.

Modern structures are routinely designed using high fidelity numerical models where the loads and structural response over the entire life cycle of a structure are simulated. The modelling research encompasses the development of methods for spatial discretisation, e.g. finite element, boundary element and smooth particle hydrodynamics methods, as well as constitutive models for materials which include damage and failure. This includes the probabilistic finite element method which allows for uncertainty quantification, uncertainty propagation, assessment of risk and interactions.

Brunel contributes to all work packages within the EXTREME project and is the leading academic partner in material model and computational methods development. This includes development of new multi-scale anisotropic constitutive models for analysis of dynamic response of composites and the simulation tools improvements, which are addressing the challenges such as treatment of mesh dependency, localisation and softening, multi-scale modelling using coupled FEM/SPH discretisation, alternative treatment of damage and fracture etc. The ultimate objective of these activities is improvement of predictive capabilities of the simulation tools for dynamic response of composites, which will be validated for the relevant cases, developed within the consortium by our industrial partners. Brunel University London team is also working on development of novel material characterisation techniques for dynamic testing and smart sensing of composite materials, using the embedded optical fibre sensors.
