Extended isogeometric boundary element method (XIBEM) for two-dimensional Helmholtz problems (2013)
Journal Article
Peake, M., Trevelyan, J., & Coates, G. (2013). Extended isogeometric boundary element method (XIBEM) for two-dimensional Helmholtz problems. Computer Methods in Applied Mechanics and Engineering, 259, 93-102. https://doi.org/10.1016/j.cma.2013.03.016

Isogeometric analysis is a topic of considerable interest in the field of numerical analysis. The boundary element method (BEM) requires only the bounding surface of geometries to be described; this makes non-uniform rational B-splines (NURBS), which...

On the formulation of thermodynamically-consistent viscoplastic-damage constitutive models (2013)
Presentation / Conference Contribution
Birchall, T., & Osman, A. (2013, March). On the formulation of thermodynamically-consistent viscoplastic-damage constitutive models. Presented at CM13: International Conference on Computational Mechanics., Durham, UK

This paper illustrates the formulation of viscoplastic-damage constitutive models using the framework of hyperplasticity. The entire constitutive behaviour is derived from only two scalar potentials; a free energy potential and a dissipation potentia...

Analysis and Enhancement of Low Voltage Ride-through Capability of Brushless Doubly Fed Induction Generator (2013)
Journal Article
Tohidi, S., Oraee, H., Zolghadri, M., Shao, S., & Tavner, P. (2013). Analysis and Enhancement of Low Voltage Ride-through Capability of Brushless Doubly Fed Induction Generator. IEEE Transactions on Industrial Electronics, 60(3), 1146-1155. https://doi.org/10.1109/tie.2012.2190955

This paper discusses the dynamic behavior of the brushless doubly fed induction generator during the grid faults which lead to a decrease in the generator's terminal voltage. The variation of the fluxes, back EMFs, and currents are analyzed during an...
