Distinct from conventional shock models when a failure of a system or accumulation of the corresponding damage occurs immediately after a shock, we consider a setting when these consequences appear with a random delay. In our model, a shock acts directly upon the failure rate of a system. This, after a random time, can result either in a failure or in the increase in the failure rate by a random amount. We derive expressions for survival probability and the failure rate for a system. Asymptotic behavior of the failure rate is also studied in detail.
