### Overview

Following the award of his PhD in Structural Engineering (Multiaxial Behaviour, Constitutive Modelling and Finite Element Analysis of Structural Concrete) from The University of Manchester (1990) and MSc in Engineering Rock Mechanics (Imperial College, London), Roger Crouch worked on bridge analysis and the design of the Channel Tunnel with UK engineering consultants Mott, Hay and Anderson. He joined the London office of US architectural practice Skidmore, Owings and Merrill to assist in the structural design of Morgan Stanley's banking headquarters (Canary Wharf) and the redevelopment of County Hall (Westminster). Roger then took a post-doctoral scientific position at école polytechnique fédérale de lausanne, working alongside Dr John Wolf, undertaking research into the nonlinear seismic behaviour of large embankment dams (1990-1994).

He was appointed to a lectureship in structural engineering at The University of Sheffield in 1994, where he established a computational mechanics group. In 1995 Roger began a programme of research into the behaviour of concrete at elevated temperatures, funded by British Energy, BNFL and Magnox UK. This work supported key safety case studies into the structural integrity of the UK's nuclear AGR pressure vessels. Roger and his co-workers designed and built (and performed many tests in) a unique high-temperature multiaxial compression apparatus. This was featured on BBC Radio 4's Material World (01.03.07). Roger and his research team also developed bespoke nonlinear finite element analysis codes running on distributed memory multi-processor computers. His experimental and computational mechanics research projects with British Energy (then EdF) and HSE NII continued for over 15 years. During this time he led and coordinated a European research project (M_CENAS FP5) advancing a NLFE thermal creep simulation capability for nuclear reactor and containment vessels.

Roger was appointed to the Chair of Civil Engineering at Durham University in 2005. In 2009, he was invited by the UK Nuclear Inspectorate to be the leading academic specialist for a safety-critical structural integrity study on the pre-stressed boiler closure units within UK AGR pressure vessels. Roger took over as Head of the School of Engineering and Computing Sciences at Durham in 2010 prior to taking up the Deanship (School of Engineering, Mathematics & Computer Science) at City University in 2013.

## Research

Roger has specialist skills in the development of parallel finite element-based analysis codes and computational plasticity models (in particular, accurate elasto-plastic stress integration algorithms and continuum-discontinuum material bifurcation investigations). He was the first to create an implicit nonlinear fluid-structure interaction code using the Scaled Boundary Finite Element method to capture the dynamic far-fi eld for large-scale 3D seismic analyses.
