Profile

David Wagg was awarded his BEng degree and PhD (at the Centre for Nonlinear Dynamics) from University College London. From 1998 until 2000 he was a postdoctoral researcher at the Earthquake Engineering Research Centre at the University of Bristol.

In 2000 he was appointed as a Lecturer in the Department of Mechanical Engineering at the University of Bristol and he became Professor there in 2008. From 2004-2009 he was an EPSRC Advanced Research Fellow. In July 2013 he moved to the University of Sheffield to take up a chair in Nonlinear Dynamics.

Professor Wagg's research is focused on understanding and controlling nonlinear structural dynamics. He is currently PI for the £4.2M EPSRC funded Engineering Nonlinearity Programme Grant, which is a consortium of five universities and eight industrial partners. He has published extensively in the topic area including the book Nonlinear Vibration with Control (Springer, 2009), which is one of the first to describe using nonlinear modelling and control for structural dynamics.

Research

The performance of engineering structures is governed by how well they behave in their operating environment. For a significant number of engineering sectors, such as wind/wave power generation, automotive, medical robotics, aerospace and large civil infrastructure, dynamic effects dominate the operational regime. As a result, understanding structural dynamics is crucial for ensuring that we have safe, reliable and efficient structures.

Professor Wagg's research is focused on understanding and controlling nonlinear structural dynamics. Nonlinearity occurs quite naturally in many applications, but despite this it has traditionally been avoided in the design of engineering systems. However, the performance envelope for all engineering structures is being pushed in response to the urgent societal need to find technological solutions for global issues such as climate change, and as a result understanding and controlling nonlinearity is becoming increasingly important in many engineering applications. A current topical example is the dynamics of large wind turbines.

Current research activities includes both fundamental and applied work on topics such as nonlinear resonance, semi-active damping, and morphing structures. Some of this relates to, so called, smart technologies, where control and feedback are used to give some form of "intelligent" behaviour to the structure. Other related work includes active vibration control, energy harvesting and energy efficient structures. Much of Professor Wagg's research includes experimental testing and, in particular he has been involved in new developments of hybrid testing such as hardware-in-the-loop and real-time dynamic substructuring. This has particularly useful application in testing for large structures, such as bridges, and other seismically excited structures.
