Submerged Cylindrical Shells Subjected to Moving Loads

摘要

An axially symmetric pressure wave expanding with constant speed along an infinitely long cylindrical shell submerged in an inviscid, incompressible fluid of infinite extent is considered. Shell-fluid interaction problems involving loads moving with constant speed have been solved by transforming to a coordinate system moving with the wave speed at the wave front. Such solutions are referred to as steady-state because an observer traveling with the wave speed would presumably see a constant pattern both ahead and behind the wave front. In this paper, the complete initial value problem is formulated and the solution is presented as the sum of a complementary and a particular solution. The steady-state solution is also constructed.
