Additional information

Numerical modelling of elastodynamic-wave scattering by local changes in material properties or geometric discontinuities is long-standing and computationally-challenging problem. Paper demonstrates novel and efficient numerical technique for solving 2D-scattering problems in isotropic media that minimises spatial modelling domain. Follow-on publication (Velichko & Wilcox, J. Acoust. Soc. Am., 128, 1004-14, 2010) generalised technique to 3D and guided-wave scattering problems. Latter formulation was extensively used in EPSRC project (EP/G052069/1, £178k, 2009-12) to investigate large populations of defect morphologies. Paper is in top 0.1% of most-cited in journal since publication (Web of Science, 29/10/2013) and identified as research group highlight in REF5.
