- Efficient and robust constitutive models underpin engineering stress analysis. Many materials exhibit non-linear behaviour, often in the form of elasto-plastic deformation. Watershed paper on using Non-Uniform Rational B-Spline (NURBS) surfaces to represent yield envelopes for elasto-plastic constitutive models, providing a new modelling framework. Unlike existing methods, the approach can be applied to different materials without code modification – provides greater efficiency when switching between materials. Two follow-on papers in top journals: dro.dur.ac.uk/21770/ and dro.dur.ac.uk/24276/. Subject of invited talk at Hohai University (China) and presented at international conferences, including COMPLAS 2017 (Barcelona, congress.cimne.com/complas2017) and NUMGE 2018 (Porto, numge2018.pt).
