Impact oscillator is a periodically excited mechanical system with one degree of freedom whose mass can impact against a stop. This paper explains the dynamics of the system, when the stop stiffness changes from zero (linear oscillator), to infinity (strongly nonlinear impact oscillator). The development of the system nonlinearity is shown on regions of periodic and chaotic impact motions depending on the excitation frequency and the static clearance between the mass and the stop.
