Summary on Grant Application Form |

For the past 30 years there have been significant advances in mathematical modelling of the ultrasonic non-destructive techniques (NDT). The upsurge of interest in this field is due to the fact that with modern computers a practical ultrasonic examination can e simulated in less time and for less money whilst at the same time occupying much less laboratory space than castings for physical collaboration tests would take. The purpose of this proposal is to develop new mathematical models of ultrasonic wave propagation in realistic transversely isotropic materials, with a view to creating innovative algorithms which allow to compute solutions of the elasto-dynamic equations for such materials hundreds times faster than the full numerical schemes currently in use. Our aim is to improve the ability to describe ultrasonic fields by fully utilising the fact that even broad-band pulses generated by industrial transducers contain mainly high frequencies. As the result, we intend to develop an efficient algorithm based on high-frequency asymptotics which would allow us to simulate the propagation of ultrasonic pulses radiated by a point source acting on the surface of half-space filled with a realistic transversely isotropic material, e.g. an austenitic steel used in the UK nuclear industry.
