The light fluid loading limit for fluid/solid interactions

Many elastodynamic solutions exist for wave interactions with defects upon or within an elastic half space bounded above by a vacuum. The aim of this paper is to significantly widen the scope of these solutions by showing that they can be directly utilised, when the vacuum is replaced by a fluid, to find the leading order acoustic (or elastic) responses in the light fluid loading limit. Using the procedure developed here one can take virtually any elastodynamic solution and use it to generate the leading order solution for a fluid loaded elastic solid.
