Nonlinear Dynamics: Mathematical Models for Rigid Bodies with a Liquid

by Ivan A. Lukovsky, Peter V. Malyshev (Translator)

Overview

This book is devoted to analytically approximate methods in the nonlinear dynamics of a rigid body with cavities partly filled by liquid. It combines several methods and compares the results with experimental data.

It is useful for experienced and early-stage readers interested in analytical approaches to fluid-structure interaction problems, the fundamental mathematical background and modeling the dynamics of such complex mechanical systems.
