DEVELOPMENT OF A FREQUENCY-DOMAIN BOUNDARY ELEMENT METHOD FOR 3-D POROELASTODYNAMICS IN GENERAL ANISOTROPY

Application of Boundary Element Method to 3 D Submerged Structures With Open Ends (RESEARCH NOTE)

This paper presents a three dimensional application of direct Boundary-Element Method (BEM) for computing interaction of sinusoidal waves with a large submerged open bottom structure near the floor with finite depth. The wave diffraction problem is formulated within the framework of linearized potential theory and solved numerically with direct BEM. A computer program based on BEM is developed ...

General time-dependent analysis with the frequency-domain hybrid boundary element method

The paper presents an attempt to consolidate a formulation for the general analysis of the dynamic response of elastic systems. Based on the mode-superposition method, a set of coupled, higher-order differential equations of motion is transformed into a set of uncoupled second order differential equations, which may be integrated by means of standard procedures. The first motivation for these t...

A General Boundary Element Formulation for The Analysis of Viscoelastic Problems

The analysis of viscoelastic materials is one of the most important subjects in engineering structures. Several works have been so far made for the integral equation methods to viscoelastic problems. From the basic assumptions of viscoelastic constitutive equations and weighted residual techniques, a simple but effective Boundary Element (BE) formulation is developed for the Kelvin viscoelastic...
