Stress wave propagation in orthotropic laminated thick-walled spherical shells

This paper presents an elastodynamic solution for stress wave propagation in an orthotropic laminated spherical shells with arbitrary thickness. The elastodynamic equation for each separate orthotropic spherical shell is solved by means of finite Hankel transforms and Laplace transforms. Then by using the interface continuity conditions between layers and the boundary conditions at the internal and external Surfaces of the laminated shells we determine the unknown constants involved. Thus an exact solution for stress wave propagation in orthotropic laminated spherical shells subjected to arbitrary radial dynamic load is obtained. (C) 2002 Elsevier Science Ltd. All rights reserved.
