Modeling and Simulation of Underwater Shock Problems Using a Coupled Lagrangian-Eulerian Analysis Approach
Abstract
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.
