Abstrakt: Engineering models to estimate a life of structure components which are simultaneously subjected to aggressive hydrogen environment influence and cycling, substantially, use two different approaches to problem-solving, i.e. the influence of aggressive hydrogen environment on material and the fatigue. A developed engineering model to estimate the life of structure components assumes that either the influence of aggressive hydrogen environment, or the fatigue initiates a local fracture of structure component. The engineering model enables a calculating of a structure component life.
