Abstract:

The axially symmetric pressure signal produced by the longitudinal impact of a semi-infinite elastic cylindrical shell upon a rigid obstacle is determined by using membrane theory. In the equivalent problem for a solid cylindrical rod, a Laplace transform was used, and the major term of the solution was determined by an asymptotic approach. Proceeding along a similar plan in the case of the shell, it was possible to obtain not only the leading term of an asymptotic expansion for large values of the time, but also further terms. Consequences of the use of the membrane theory are discussed. Author
