Linear dynamic simulations


The objective of linear dynamics, beyond the modal analysis described in a dedicated chapter, is to examine the response of a structure to a dynamic excitation of "small" amplitude. This excitation may be of a transitory, harmonic (or spectral), or randomized nature. It can also be called vibration analysis. The stress or displacement results can thus be used to dimension the structure. It is fundamental to take great care with the damping parameter with this type of simulation…
