Energy-based method of fatigue damage cumulation
Source abstract
Abstract
Abstract The study presents the results of low-cycle fatigue tests on AW-2024 aluminium alloy specimens under constant amplitude and multistage loading conditions. As expected, significant hardening of the material was observed in both cases. The tests confirmed that cyclic properties of AW-2024 alloy under multistage loading conditions can be represented based on the results of tests under constant amplitude conditions for the same alloy. The basis for a new fatigue damage cumulation method was formulated based on a comparative analysis of the test results. The main feature of the proposed method consists in including into the analysis the cyclic hardening of AW-2024 alloy during fatigue life calculation. An experimental verification of the method proved its practical applicability. A comparative analysis of the results for a standard Palmgren-Miner hypothesis and the new approach demonstrated the advantages of using the new method.
