A Study of Combined Graphical Acoustic Computing and the Depth Peeling Technique on Acoustic Backscattering of Multiple-Layered Structures

An efficient graphical acoustic computing (GRACO) method is introduced. Referring to the rendering of semi-transparent objects, depth peeling (DP) technique compounded with GRACO method, forming a combined and DP (GRACO–DP) consider backscattering multiple-layered structures in which contributions inner are included. After that, some examples GRACO–DP tested evaluate accuracy efficiency such methods. Through impedance sphere benchmark models, can acquire results higher good consistency compared traditional KA method. Also, TS pair circular plates determined by GRACO, GRACO–DP, finite element (FEM). The show that fit better FEM results. Moreover, ribbed double shell predicted both GRACO–DP; features Bragg wave scattered periodically arranged ribs be spotted from result GRACO–DP.
