This text is concerned with the analysis of structures subjected to dynamic loads. Dynamics in this context means time-varying. Both application of load and removal of load necessarily vary with time. Hence, the internal stresses and the resulting deflections are also time-dependent or dynamic in nature. In the real world, no loads that are applied to a structure are truly static. All bodies possessing mass and elasticity are capable of vibration. Thus most engineering machines and structures experience vibration to some degree and their design generally requires consideration of oscillatory behavior. The effects of vibration are very common in our daily life. We live on the beating of our hearts. Planetary motion is also another example of vibration. These motions are called periodic motions (periodic motion is a motion that repeats itself regularly after a certain interval of time).
