Abstract  In the literature of reliability theory, many studies have concentrated on single types of shock (e.g., aging). Previous studies have investigated the following cases. (1) When a shock of a given magnitude is applied to a unit, it immediately fails. (2) When the shocks are additive and the total shock magnitude is greater than K, a unit fails. (3) When the shocks are not additive, and the magnitude of a given shock is greater than K, the unit fails. In this paper, we suppose case (2). In addition, suppose two types of shocks are applied to a single unit (i.e., not a single shock type). Each type of shock occurs by a different stochastic process, and the respective magnitude of each type of shock shows a different probabilistic distribution. We perform damage analysis for a single unit when both types of event occur by general stochastic processes and both shock magnitudes follow general probabilistic distributions. Thus, we perform a detailed analysis while the events occur by Poisson processes and both shock magnitudes show different exponential distributions.
