In this paper, we study the oscillatory behavior of second-order forced impulsive delay differential equations with mixed nonlinearities. By using Riccati transformation technique, integral averaging method and some inequalities, we obtain sufficient conditions for oscillation of all solutions. Finally, two examples are presented to illustrate the theoretical results.
