提出了一种新的依赖历史的累积损伤现象学模型。这是一个随机模型。该模型将疲劳和磨损中遇到的变异性的主要来源作为其结构的固有部分。该模型的通用性比目前使用的模型更符合疲劳磨损过程的复杂性。这也意味着，当使用当前模型时，在寿命预测中经常遇到的不准确性并不令人惊讶，并且不能使用这些模型大幅减少。
A new history-dependent phenomenological model of cumulative damage is presented. It is a stochastic model. The model includes as an inherent part of its structure the major sources of variability encountered in fatigue and wear. The generality possessed by the model is much more in accord with the complexity of fatigue and wear processes than possessed by models in current use. It also implies that the frequent inaccuracies encountered in life prediction when using current models are not surprising and cannot be substantially reduced using such models.
