• New formulation based on the principle of power balance as the basic method for deriving equations of motion for one- and multi-degree-of-freedom models. This approach allows for direct application of Lagrange's equations as an alternative.
• Equal emphasis on Matlab and Mathcad, including identification of errors commonly made by students when each program is used for vibration analysis.
• Thorough treatment of FFT technology, and its application to vibrations.
• Analysis of transient response using frequency domain convolution, including avoidance of aliasing, wraparound, and leakage errors.
• Experimental identification of system parameters for one-degree-of-freedom systems.
• Experimental model analysis for multi-degree-of-freedom systems.
• Extensive discussions of physical significance of results.
• Uses recent research in many examples, such as mode localization in bladed disks and beams, and dynamic stability of pipes.
• Study of continuum vibrations does not require knowledge of partial differential equations.
• The primary tool for continuum vibrations is Ritz series expansions, which is applied to axial, torsional, and flexural vibration of bars having masses, springs, and dashpots at arbitrary locations.
• New formulation of modal analysis for arbitrarily damped, but non-gyroscopic, systems leads to symmetric state-space eigenvalue problem.
• The approach builds on familiarity with undamped modal analysis, and is highly accessible.
• Underdamped and overdamped modes are explained relative to analogous behavior of one-degree-of-freedom systems.
