| Abstract | Changes in the mechanical properties of a solid plate, induced by fatigue damage, will influence the features of ultrasonic Lamb wave propagation such as dispersion, amplitude and attenuation. The feasibility of using ultrasonic Lamb wave spectra to assess fatigue damage in solid plates was briefly discussed. For a given aluminum (2024-T3) sheet, the amplitude-frequency curves before and after cyclic loading were measured with the established experimental setup for ultrasonic Lamb waves. Based on the data measured, the ultrasonic Lamb wave spectra diagrams were established. Clear difference between the two spectra diagrams before and after cyclic loading could be found. It is concluded that ultrasonic Lamb wave spectra may be used to effectively assess the early stages of fatigue damage in solid plates. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
