复杂机械系统中结构材料的性能和寿命限制通常是基于对失效的恐惧而建立的。避免结构故障的传统方法通常涉及广泛的定期检查，冗长的维护过程，以及高度保守的“运行，不运行”操作决策，所有这些都可能严重损害系统的准备状态。本文总结了当今先进系统的典型寿命管理过程，然后介绍了一种称为材料损伤预测的替代寿命管理方法的关键要素。
Performance and life limits for structural materials in complex mechanical systems are often established based heavily on a fear of failure. Conventional approaches for avoiding structural failure often involve extensive periodic in spections, lengthy maintenance processes, and highly conservative “go, no-go” operational decisions, all of which may significantly impair system readiness. This article summarizes a typical present-day life-management process for an advanced system and then presents the key elements of an alternative life-management approach known as materials damage prognosis.
