(The progression from Structural dynamics (linear))

!non-linear objects

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
