Space-Time Discretized Retarded Potential Boundary Integral Operators: Quadrature for Collocation Methods

Publikováno v: SIAM Journal on Scientific Computing. 41:A3860-A3886

We propose a novel discretization method for time domain boundary integral equations of the three-dimensional wave equation. The basic idea of the discussed approach is to treat time as if it were ...

On the space-time discretization of variational retarded potential boundary integral equations

Autor: Martin Schanz, Dominik Pölz

This paper discusses the practical development of space-time boundary element methods for the wave equation in three spatial dimensions. The employed trial spaces stem from simplex meshes of the lateral boundary of the space-time cylinder. This appro

High order exact geometry finite elements for seven-parameter shells with parametric and implicit reference surfaces

Autor: Martin Schanz, Michael Helmut Gfrerer

Publikováno v: Computational Mechanics. 64:133-145

We present high order surface finite element methods for the linear analysis of seven-parameter shells. The special feature of these methods is that they work with the exact geometry of the shell reference surface which can be given parametrically by

Fast multipole method for poroelastodynamics

Autor: Martin Schanz

Publikováno v: Engineering Analysis with Boundary Elements. 89:50-59

Wave propagation phenomena occur in reality often in semi-infinite two-phase (porous) regions. It is well known that such problems can be handled well with the poroelastodynamic Boundary Element Method (BEM). But, it is also well known that the BEM w
