摘要：

Based on the critical plane approach, a new damage parameter for multiaxial fatigue damage is presented. Both components of strain and stress are considered in this parameter. Thus, a new multiaxial fatigue damage model is given based on the critical plane approach. The capability of fatigue life prediction for the proposed fatigue damage model is checked against the experimental data of Hot-rolled 45 Steel, S460N Steel, 1045HR Steel, 30CrMnSiNi2A alloy steel, and GH4169 alloy at elevated temperature, and the predicted results are compared with results from common multiaxial fatigue model. It is demonstrated that the proposed criterion gives better satisfactory results for all the five checked materials. (C) 2008 Elsevier Ltd. All rights reserved.
