In this paper, we consider numerical solutions of a time domainacoustic-elastic wave interaction problem which occurs between a boundedpenetrable elastic body and a compressible inviscid fluid. It is also calledthe fluid-solid interaction problem. Firstly, an artificial boundary isintroduced to transform the original transmission problem into a problem in abounded region, and then its well-posed results are presented. We then employ asymmetric interior penalty discontinuous Galerkin method for the solution ofthe reduced interaction problem consisting of second-order wave equations. Apriori error estimate in the energy norm is presented, and numerical resultsconfirm the accuracy and validity of the proposed method.
