Static analysis of functionally graded plates using the high-order shear deformation theory by MITC3 plate elements having strains smoothed on edges

The paper presents an efficient 3-node triangular finite plate element for static analysis of functionally graded plates using the high-order shear deformation theory (HSDT). The strain fields of the plate elements, which use the MITC3 technique to remove the shear-locking phenomenon, are smoothed on the edges of the elements to improve numerical demonstration.

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....
