Sommario/riassunto

In 1848 seventy-six slaves from the nation's capital hid aboard the schooner Pearl in an attempt to sail to freedom in Pennsylvania. When bad weather forced them to anchor, the slaves and the ship's crew were captured and returned to Washington. This work ranges from the preparations for escape to the participants' trial.

Nota di contenuto

Introduction to the Linear Theory of Elastoelasticity -- Some Solutions of Dynamical Problems for Finite Length Elasticity and Piezoceramic Cylinders with Inhomogeneous Properties (based on 3D theory) -- Electroelastic Waves Propagation in Heterogeneous Piezoceramic Hollow Cylinders -- Electroelastic Vibrations Heterogeneous Piezoceramic Hollow Spheres.

Sommario/riassunto

This book presents various dynamic processes in non-uniform piezoceramic cylindrical and spherical bodies based on numerical methods. It discusses different variants of nonhomogeneous structural polarized piezoceramic materials in the shape of cylinders and spheres, and highlights the validation of the reliability of the results obtained by numerical calculations. The content is based on an outlined theory and methods of three-dimensional electroelasticity problems.
