The crack growth process is described by Paris' equation, stress intensity factor (SIF) is determined by the direct method. Testing of the algorithm is executed on the problem of the development of an elliptical crack in a prismatic body under the action of cyclic loading.encyclic loading conditioncrackfracture mechaniclifetimespatial problemsemianalytic finite element method (SFEM)циклическая нагрузкатрещинамеханика разрушенияресурспространственная задачаароуаналитический метод конечных элементов (ПМКЭ)кафедра будівельної механікиArticle539.421
