Stiffness component of a dynamic system is contributed by deforming element under certain external force. The magnitude of the element’s stiffness is dependent of its material properties, cross section, length and end restraint conditions.
The stiffness component for series and parallel system is different in terms of calculation method, and we can derive it from the displacement of idealized structure.
The following introduces the stiffness component in a dynamic system. Watch the video above for full details.
