Frequency and Time Domain Response Calculations,13 for a discrete system description and Eq. 5.32 for a continuous system description). In this chapter we shall present possible solution strategies. Basically, one is free to choose whichever approach is deemed most suitable solution strategy, e.g. with respect to efficiency or accuracy.

One and Two Degree of Freedom Systems,in the field of structural dynamics. Nonetheless, the case of a single harmonic force on simple systems is an illustrative overture to the ensuing chapters in this book. It is taken for granted that forces are rectilinear.

Damping,em, as this is its slowest possible free motion, and therefore it requires the least amount of energy exchange between inertia and stress fluctuations. The reason for the decay of the motion (diminishing of kinetic energy) is ascribed to damping forces within the system or between the system and its surrounding air or water.

The Normal Mode Method,In Chapter 4 we developed the equilibrium condition.M.r̈(t)+C.ṙ(t)+K.r(t)=R(t).for a general discrete system with a chosen set of degrees of freedom . = [............]. and subject to a corresponding set of external loads . = [............]..
