© 2018 Elsevier Ltd Modelling is increasingly relied on for the design and qualification of ultrasonic inspections applied to safety-critical components. Numerical methods enable the simulation of the ultrasonic interaction with realistic defect morphologies; however, the computational requirements often limit their deployment. The hybrid simulation technique, which combines semi-analytical and numerical methods, realises the potential of high fidelity numerical modelling without the limiting computational factors. The inspection of thick section components for near-backwall surface-breaking defects results in large propagation distances, making them a key application of hybrid modelling. This work presents a methodology for efficiently simulating the ultrasonic inspection of complex surface-breaking defects using a hybrid model. The model is initially verified against full numerical simulation; further validation is presented by comparison to an experimental scan over an artificially machined surface-breaking notch. The potential of the new hybrid method is then demonstrated by carrying out a Monte Carlo analysis on the scattered field from surface-breaking defects with randomly rough surfaces and the results are compared to the Kirchhoff approximation.

Pipe wall loss caused by corrosion can be quantifiedacross an area by transmitting guided Lamb waves throughthe region and measuring the resulting signals. Typically thedispersive relationship for these waves, which means thatwave velocity is a known function of thickness, is exploited,enabling the wall thickness to be determined from a velocityreconstruction. The accuracy and quality of this reconstructionis commonly limited by the angle of view available from thetransducer arrays. These arrays are often attached as a pairof ring arrays on either side of the inspected region, and dueto the cylindrical nature of the pipe, waves are able to travelin an infinite number of helical paths between any two transducers.The first arrivals can be separated relatively easily bytime gating, but by using just these components the angle ofview is severely restricted. To improve the viewing angle, it isnecessary to separate the wavepackets. This paper provides anoutline of a separation approach: initially the waves are backpropagatedto their source to align the different signals, then afiltering technique is applied to select the desired components.The technique is applied to experimental data and demonstratedto robustly separate the signals
