A Green"s Function Time-Domain BEM of Elastodynamics - Topics in Engineering Vol 31 by C. Richter Download PDF EPUB FB2

This "book on disk" demonstrates how the transient Green's Function of the elastodynamic 2D Lamb's problem is derived and used to develop a fast and accurate time-domain BEM.

The Green's Function is purely algebraic without any integrals and is presented in numerically applicable form for the first by: 6. a time domain BEM but very often the main motivation as, e.g., in earthquake engineering.

The first boundary integral formulation for elastodynamics was published by Cruse and Rizzo (). This formulation performs in Laplace domain with a sub-sequent inverse transformation to the time domain to achieve results for the transient behavior.
