✦ Synopsis

A theoretical solution for an orthotropic thick cylindrical shell under arbitrary impact load is presented by making use of the "nite Hankel transform and the Laplace transform. Dynamic formulas for a cylindrically orthotropic problem are derived and results are obtained for some practical examples, in which an orthotropic thick cylindrical shell is subjected to a sudden load and an exponential decaying shock pressure. Finally, a dynamic "nite element for the same problem is also carried out by applying the Algor (Super sap) "nite element analysis system. Comparing theoretical solution with "nite element solution, it can be found that two kinds of results obtained by making use of two di!erent solving methods are suitably approached. Thus, it is further concluded that the method and computing process of the theoretical solution are e!ective and accurate.
