This proposal seeks funding for a three year research programme into the use of waves which are guided by structural features for the detection of defects, such as cracks or corrosion, in or near the features. The idea is supported by practical observations that a butt weld between two plates has a significant guiding effect, clearly tending to retain the energy of the fundamental extensional wave in and near the weld. The work will include the development of a modelling capability to study and understand the nature of guided waves in welds and other structural features, followed by a study of the application of the model to butt welds and other realistic features of interest to the industrial partners. The proposal is being submitted within the UK Research Centre in NDE (RCNDE) to the targeted research programme, the funding for which is earmarked by EPSRC for industrially driven research.

这项提议寻求为一项为期三年的研究方案提供资金，该方案旨在利用由结构特征引导的波来检测特征内或附近的缺陷，如裂缝或腐蚀。这一观点得到了实际观察的支持，即两个板之间的对接焊缝具有显著的导向作用，显然倾向于将基本伸展波的能量保留在焊缝内和焊缝附近。这项工作将包括开发建模能力，以研究和了解焊缝和其他结构特征中导波的性质，然后研究模型在对接焊缝和工业合作伙伴感兴趣的其他现实特征中的应用。该提案正在英国NDE研究中心(RCNDE)内提交给有针对性的研究计划，EPSRC专门为工业驱动的研究提供资金。
