Then, several types of periodic steady-state response are identified and determined by applying a methodology, that is suitable for piecewise linear systems with time-periodic coefficients and excitation. This methodology is comple

The imposition of suitable boundary conditions at the instants of impacts eliminates the singularities introduced by the transformations, and the smoothened problem is solved numerically. Numerical analysis reveals vibro-impact solutions of complicated form and interesting bifurc
