Abstract

In recent years, mesh-free semi-analytical technique called distributed point source method (DPSM) has been increasingly used in computing ultrasonic wave field. A generalized computational method has been used for simulation in generic anisotropic plate using a comprehensive formulation of Green’s function. The Green’s function required for the implementation of DPSM is formulated using Fourier Transform method. Wave fields in unidirectional composite materials with 0 and 90-degree fiber orientations are reported using DPSM followed by generalized mathematical formulations. DPSM is implemented for multilayered anisotropic plates. Applying generalized mathematical formulations, NDE of multilayered anisotropic plate is simulated and reported in this article. Virtual NDE experiments of anisotropic plates in Pulse-Echo mode are simulated using a circular transducer of central frequency ~1MHz. Wave fields inside both the fluid and the solid media were calculated.
