By assembling the square lattice arrays of “+” shaped steel rods, an underwater acoustic composite lens consisting a convex and slab is proposed to achieve convergence waves. In order study focusing ability, numerical simulations experiments in silencing pool are carried out among range frequencies between 15 kHz 25 kHz. As result, 3-D wave inspiringly achieved observed. Particularly, vertically extended from 2-D lens, but it found be able focus waves three-dimensional manner. Comparisons...
The differential quadrature method has been developed to calculate the elastic band gaps from Bragg reflection mechanism in periodic structures efficiently and accurately. However, there have no reports that this successfully used of locally resonant structures. This is because, process using structures, non-linear term frequency exists matrix equation, which makes it impossible solve dispersion relationship by conventional matrix-partitioning method. Hence, an accurate efficient numerical...
In this paper, a 3D semi-analytical method is proposed by introducing the Durbin’s Laplace transform, as well its numerical inversion method, state space approach and differential quadrature to analyse transient behaviour of functionally graded material cylindrical panels. Moreover, investigate effectiveness solution, four boundary conditions are used undertake analyses. Comparing with other theoretical methods from literatures, we see better agreements in natural frequencies. Besides,...
