A variationally coupled FE-BE method for transient problems. (English) Zbl 0796.73056

A variationally coupled finite element-boundary element method is developed for transient problems. A single variational statement is obtained for the entire domain, and the unknown tractions, which may be discontinuous on the interface and are often a source of difficulties, are eliminated. Moreover, no interface conditions need be taken into consideration at the level of the discretized equation. The discrete equations for the coupled system can be obtained directly without any intermediate steps.
