03.1 - Materials issues, Fatigue and Damage ToleranceXFEM-BASED FRACTURE MECHANICS ANALYSIS OF AERONAUTICAL STRUCTURES AFFECTED BY RESIDUAL STRESSESI. Rivero Arevaloš, J. Gomez-Escalonilla Martinš, V. Ramirez Gonzalez˛, A. Garcia Martinez-Pardo˛, D. Garijo Hernandez, IMDEA Materials Institute, Spain; šAirbus Defence and Space, Spain ;˛Safran Engineering Services, Spain Residual stresses may influence the behavior of a crack growing in a metallic structure. In order to ensure the structural robustness of a design affected by residual stresses, the development of accurate numerical models able to predict this influence is of major importance for industry nowadays. In this work, the eXtended Finite Element Method (XFEM) has been applied to simulate this phenomenon. |
