Summary on Grant Application Form |

The aim of this proposal is to develop and validate experimentally new mathematical models of angle beam ultrasonic transducers, with a view to creating an accurate computer code which is hundreds to thousand times faster than the full numerical schemes currently in use and which has a wider range of applicability than the currently used approximate codes. This will assure better exploitation of available instrumentation for quantitative NDT of industrial materials through improved interpretation of ultrasonic inspection data. The insight gained is likely to lead to improved design and development methods for new instrumentation. In the first instance we propose to concentrate on a specific industrial problem relating to ferritic steels which are used in the UK nuclear industry for the construction of the nuclear power pressure vessels and in the UK chemical industry for the construction of high pressure reaction vessels. The prime objective is to develop further the code developed at the Centre for Waves and Fields for efficient simulation of waves and pulses radiated by uniform compressional circular and rectangular probes directly coupled to the inspection surface -by adding to it inexpensive and accurate subroutines for simulating ultrasonic fields radiated by angle beam rectangular and elliptic crystal probes coupled to a ferritic component directly or by a thin viscous layer. We propose to deal with arbitrary angles requiring modelling propagation of both direct and edge bulk compressional and shear waves as well as Rayleigh waves. We aim to make a thorough comparison of the performance of our code with both exact numerical results and experimental data.
