Modeling and Simulation of Underwater Shock Problems Using a Coupled Lagrangian—Eulerian Analysis Approach

[摘要] The application of coupled Lagrangian—Eulerian analysis to various types of underwater shock problems was investigated, with the verification and validation of this analysis approach in mind. Analyses were conducted for a simple TNT detonation problem and for the classical problems of an infinite cylindrical shell and a spherical shell loaded by a plane acoustic step wave. The advantages, disadvantages, and limitations of this approach are identified and discussed.
