标题：APPLICATION OF TWO-PARAMETER FATIGUE CHARACTERSITICS IN FATIGUE PERSISTENCE CALCULATIONS OF STRUCTURAL COMPONENTS UNDER CONDITIONS OF A BROAD SPECTRUM OF LOADS
摘要：The paper presents an original method of calculation of the fatigue persistence based on the adoption of the load spectrum in the form of a correlation table,two-parameter fatigue characteristics and the linear hypothesis of fatigue damage summation.The calculation results by the proposed method were compared with the results of fatigue tests programmed for node-seal construction.On the basis of a comparative analysis of the test results and calculations conclusions regarding the usefulness of the proposed method to evaluate the fatigue persistence of components have been reached.
