“…Again a truncation factor T = 2 is applied. No discontinuities can be seen at the interface between the two subdomains Ω (1) and Ω (2) , to 340 for subdomain Ω (1) and from 24 to 568 for subdomain Ω (2) at 200Hz, and from 28 to 452 for subdomain Ω (1) and from 48 to 756 for subdomain Ω (2) at 400Hz. As can be seen from those figures, the WBM with two subdomains obtains engineering accuracy very fast, but stagnates at a lower accuracy as compared to the WBM with one subdomain.…”

“…The top and the bottom layer contain material 1, the middle layer consists of material 3 of Table 200Hz absolute value of the shear stresses in the three layers calculated with the WBM at 600Hz using the potential formulation. The WB model contains 408 wave functions of each kind in subdomain Ω (1) and Ω (2) and 388 wave functions of each type in subdomain Ω (3) . Continuity is clearly obtained across the interfaces.…”

“…The classic Finite Element Method (FEM) is a well-framed and accurate method that requires a finite element discretisation of the whole model, implicitly limiting its application range [1,2,3,4,5]. Alternative formulations have also been proposed to reduce the computational effort of the method [6,7,8].…”
