This is a proposal for a multi-departmental multidisciplinary project, involving applied mathematicians, electrical engineers and a Visiting Fellow of world renown to meet a real industrial need and develop a state-of-the-art probabilistic approach to sizing rough corrosion cracks to ensure fitness for purpose over the life of a cracked components. The primary aim is to provide a much needed rule-of-thumb for inclusion in technical justification of ultrasonic NDT of misorientated corrosion cracks. Such justifications provide a key input to SI assessment of safety-critical components where the possible presence of rough cracks is a major concern. Our prime objective is to estimate the effect of relatively small roughness on ultrasonic echoes. We propose to identify the worst case roughness and misorientation, determine the margins of detection, provide physical insight and define regime of validity of our model. In the first instance, we propose to concentrate on a specific industrial problem relating to isotropic materials, such as ferritic steels used in UK industry for construction of the nuclear power pressure vessels and chemical high-pressure vessels. This specific study is a basis for future investigation into a broad range of similar SI problems, involving materials of a more complicated structure, such as austenitic steels, fibro-reinforced composites, ceramics etc as used in construction, oil and gas industries and transport.EngProg\
