Axisymmetric Scaled Boundary Finite Element Formulation for Wave Propagation in Unbounded Layered Media

Wave propagation in unbounded layered media with a new formulation of Axisymmetric Scaled Boundary Finite Element Method (AXI-SBFEM) is derived. Dividing the general three-dimensional unbounded domain into a number of independent two-dimensional ones, the problem could be solved by a significant reduction in required storage and computational time. The equations of the corresponding Axisymmetri...

WAVE ACOUSTIC PROPAGATION FOR GEOPHYSICS IMAGING, FINITE DIFFERENCE vs FINITE ELEMENT METHODS COMPARISON AND BOUNDARY CONDITION TREATMENT

Imaging techniques for geophysic prospection of sea bottom are extremely demanding in terms of mathematical methods and computational resources [8]. This is because the measurements are going deeper than before, thus making the structures identification a hard task, and the datasets to be computed huge. Besides, the current trend is to analyze the images in three dimensions (3D) [4], adding an ...

A Finite Element Study of Transient Wave Propagation in Plates

National Bureau of Standards Gaithersburg, MD 20899 Studies of transient wave propagation in plates were carried out to establish a basis for the impact-echo technique as a nondestructive test for flaw detection in concrete. The surface displacements caused by stress waves generated by point impact on a plate were calculated using both the Green's function solution and the finite element method...

Analysis of electromagnetic wave propagation using 3D finite-difference time-domain methods with parallel processing

vi Abstract The 3D Finite-Difference Time-Domain (FDTD) method simulates structures in the time-domain using a direct form of Maxwell's curl equations. This method has the advantage over other simulation methods in that it does not use empirical approximations. Unfortunately, it requires large amounts of memory and long simulation times. This thesis applies parallel processing to the method so ...

Wave Propagation In Axisymmetric Structures From Finite Element Analysis

This paper describes a wave and finite element (WFE) method for the numerical prediction of wave propagation in axisymmetric structures. A small segment of the structure is modelled using conventional finite element methods, commonly using a commercial package, and the mass and stiffness matrices found. This typically involves a single shell element or, especially for laminate structures, a sta...
