چکیده انگلیسی
A new method for the automatic and simultaneous measurement of phase velocity and thickness for thin composite plates was developed based on Ping He׳s method, without any need of a priori knowledge of the material parameters. Two composites were analyzed: a block of clean epoxy and a thin specimen of glass-fiber reinforced plastic produced by resin transfer molding. The proposed method combines cross-correlation functions and iterative deconvolution for accurate measurement of times of flight and gating. The new method has demonstrated to be more accurate than conventional Ping He׳s method, and can be implemented automatically thus saving processing time and increasing accuracy.
