(The progression from Structural dynamics (linear))
Example : non linear stiffness
The relation F_0=Kx
is no more, instead it becomes non linear :
F_0=K_1x+K_3x^3
It can be though of as the stiffness depends on the amplitude of the movement !non-linear stiffness Frequency Response Function example for a stiffening object
