Presents recent developments in structural dynamics with particular emphasis on the formulation of equations of motion by finite element methods and their solution using microcomputers. The book discusses the use of frequency-dependent shape functions for realistic finite element modelling, as opposed to the approximate conventional shape functions. A useful feature of the book in handling the forced vibration problem is the separation of the solution into two parts: the steady state and transient. Advanced topics such as substructure and synthesis are viewed in a modern unified manner. A complete listing of the finite element programme NATVIB used is given.
