CRACK IDENTIFICATION IN FUNCTIONALLY GRADED MATERIAL PLATE BY WAVELET ANALYSIS OF VIBRATION MODE
In this paper, a method based on the wavelet analysis of modal vibration data is introduced to detect the cracks in the functionally graded material (FGM) plate. In practice, the modal vibration data which include the natural frequencies and mode shapes of cracked plate are usually defined by measured equipments. However, due to the unavailability of experimental data, numerical analysis with noisy modal data is used for simulation instead....

To be able to use the functionality of PRISM in full, users have to register in the system by entering their user identifi cation and password (which are not case sensitive) and clicking the REGISTER NOW menu. The registration is needed to enable the users to receive a confi rmation e-mail message when their simulations are done so that they can view the results.
