16 Sep 2013 PHASED ARRAY BEAMSTEERING IN COMPOSITE LAMINATES FOR GUIDED linear array for anisotropic wave modes is quite small and other side lobes, the wave propagation due to each transducer needs to be known. In an isotropic plate, omnidirectional point sources can be generally assumed.
In this study, a guided wave phased array beamsteering in composites, guided wave propagation varies with direction In an isotropic plate, omnidirectional point sources can be generally assumed. Using this approach, Yu and Giurgiutiu have developed a general beamforming algorithm for a 1D phased array applied
This paper describes phased array beamforming using guided waves in anisotropic composite plates. A generic phased array algorithm is presented, in which direction dependent guided wave parameters and the energy skew effect are considered. This beamforming at an angular direction is achieved based on the classic

Abstract: This thesis covers both ultrasonic guided wave mechanics and phased array principles and also combines them into ultrasonic guided wave phased array
guided wave data. The global-local inspection is performed in two steps. First, a phased array configured of a small number of SLDV scan points (for example 10?10 points in a rectangular grid array) performs inspection over the entire plate to detect and locate damage. (Figure 1a). Local areas are identified as potential
