会议名称：COMADEM 2015+X CORENDE
会议日期：1-4 December, 2015
会议地点：Buenos Aires, Argentina
会议简介：The Congress intends to invite and integrate people involved in this study area in an open forum. The purpose of the congress is to encourage and facilitate exchange of information and experiences from all regions of the world. COMADEM is the opportunity to get in touch with technologies that continuously improve and enhance the quality, reliability, safety, availability, maintainability and performance of all assets (both physical and human) for as long as possible and to derive maximum benefits with minimum risk. CORENDE is a forum to discuss the improvements in the technologies used in the evaluation of components, systems and structures: non-destructive testing, personnel certification, standards, welding inspection, maintenance and structural testing. The program will provide an unrivalled opportunity to network with representatives from globally significant research centers, industry leading companies, government organizations, professional bodies and Universities.

Tittle: Numerical study of Nonlinear S0 mode Lamb waves for the detection of material nonlinearity
Xiang Wana,c, Guang-hua Xua, b,*, Qing Zhangaand Peter-W Tsec
ABSTRACT- Nonlinear Lamb waves technique has been widely used in evaluating material nonlinearity, assessing structural degradation and detecting micro damages in thin plate-like structures. Theoretical and experimental studies on nonlinear Lamb waves have demonstrated that only specific mode pairs that satisfy phase velocity matching and non-zero power flux conditions exhibit cumulative second harmonic generation. However, there are some limitations using nonlinear Lamb wave technique based on phase velocity matching. In order to overcome these limitations, nonlinear S0 mode Lamb waves at low frequencies based on phase velocity approximate matching is proposed. The proposed method is used to detect material nonlinearity. The numerical results using our proposed method is in accordance with the results using the phase velocity matching method. And these results have proven that our proposed method is feasible and effective.
