# Professor Stephane Bordas

PhD, MSc

Professor

## Overview

Born in Paris, France in 1975, I joined the Theoretical Applied and Computational Mechanics team at Cardiff University on 1st September 2009, as a Professor.

Before this, I was a lecturer in Glasgow University Civil Engineering Department for three years (2006-2009).

Between 2003 and 2006, I was at the Laboratory of Structural and Continuum Mechanics at the Swiss Federal Institute of Technology in Lausanne, Switzerland, working under the support of Professor Thomas Zimmermann on meshfree point collocation methods and partition of unity enrichment (extended finite elements) with applications to geomechanics.

In 2003, I graduated in Theoretical and Applied Mechanics with a Ph.D. from Northwestern University under the guidance of Professor Brian Moran. My thesis, funded by the Federal Aviation Administration, concentrated on applications of the extended finite element method (XFEM) to damage tolerance analysis of complex structures, casting design and biofilm growth processes. In addition to the unique support of Professor Moran, this work would never have been possible without Professor James Conley and Professor David Chopp as well as the instruction of Professor Ted Belytschko.

In 1999, through a joint graduate programme of the French Institute of Technology (Ecole Speciale des Travaux Publics) and the American Northwestern University I complete a dual M.Sc. after a thesis work on Time Domain Reflectometry simulation to assess ground movements with Professor Charles H. Dowding.

My areas of expertise are:

Computational mechanics with an emphasis on moving discontinuities (mechanics of fracture, biofilm and tumour growth, etc.)

Method development (enriched/extended finite elements, meshfree methods, smooth strain finite elements)

Evolving discontinuities (level set methods, partition of unity enrichment

Academic research/industrial applications: bridging the gap (porting novel methods to industrial codes, real-world applications of computational mechanics and novel method development)

More recently developed areas of interest include:

High Performance Computing

Surgical Simulation

Biomechanics

Microstructurally-faithful material modelling

Multiscale simulation

Model Reduction techniques
