Structural Dynamics
Linked via "natural modes of vibration"
Modal Analysis and Eigenproblems
The core analytical step in structural dynamics is the determination of the system's natural modes of vibration, which are the characteristic, unforced responses of the system. For an undamped, free-vibration system ($\mathbf{f}(t) = 0, \mathbf{C} = 0$), the equation simplifies to:
