Computational Dynamics, 3rd edition, thoroughly revised andupdated, provides logical coverage of both theory and numericalcomputation techniques for practical applications.
The author introduces students to this advanced topic coveringthe concepts, definitions and techniques used in multi-body systemdynamics including essential coverage of kinematics and dynamics ofmotion in three dimensions. He uses analytical tools includingLagrangian and Hamiltonian methods as well as Newton-EulerEquations.

An educational version of multibody computer code is nowincluded in this new edition that can beused for instruction and demonstration of the theories andformulations presented in the book, and a new chapter is includedto explain the use of this code in solving practical engineeringproblems.

Most books treat the subject of dynamics from an analyticalpoint of view, focusing on the techniques for analyzing theproblems presented. This book is exceptional in that it covers thepractical computational methods used to solve "real-world"problems. This makes it of particular interest not only for senior/graduate courses in mechanical and aerospace engineering, but alsoto professional engineers.
* Modern and focused treatment of the mathematical techniques,physical theories and application of rigid body mechanics thatemphasizes the fundamentals of the subject, stresses the importanceof computational methods and offers a wide variety ofexamples.
* Each chapter features simple examples that show the main ideasand procedures, as well as straightforward problem sets thatfacilitate learning and help readers build problem-solvingskills
