The extended Finite Element Method (XFEM) in Abaqus is a powerful tool for fracture and crack propagation analysis. High Cycle Fatigue (HCF) crack growth, which is associated with stresses below the yield strength, is usually analyzed in the range of 10^4 to 10^7 cycles, where the failure mechanism is different from Low Cycle Fatigue (LCF).

Here is a general guideline for conducting XFEM analysis under HCF conditions in Abaqus:

Remember that HCF analysis is often based on S-N curves (Stress vs Number of cycles), and Miner's rule may be used for cumulative damage calculations.

Please note that the specifics might vary depending on your version of Abaqus and the details of your model. Also, remember to refer to the Abaqus documentation and support resources for detailed instructions and examples related to your specific needs.

However, as of my knowledge cutoff in 2021, Abaqus doesn't inherently support High Cycle Fatigue crack growth simulation using XFEM. It supports LCF crack growth using the Direct Cyclic step, but HCF is usually done by user-subroutines where the Paris law can be implemented manually for HCF crack growth. You might want to check if newer versions have introduced this feature or need a user-defined subroutine to customize your analysis.

Tahere Hosseini,

As far as I know, high cycle loading analysis is not possible in Abaqus alone. You have several solutions.

1- Using the Helius PFA plugin for composite materials

2- Using fe-safe or MSC-Fatigue for metal materials

3- Using the Pelamis plugin for metal offshore structures

4- Writing subroutines and scripts

Good luck

Performing crack growth analysis under high cycle loading using XFEM can be complex and time-consuming. It is essential to have a good understanding of fracture mechanics principles and XFEM theory.

I will mention some general points that need to be considered in modeling.

* Specify the material properties for the components involved in the analysis, including the elastic modulus, Poisson's ratio, and fatigue properties such as the fatigue limit and S-N curve.

* Generate the geometry of your model, including any initial cracks or defects that you want to analyze.

* Create a suitable mesh for your model, ensuring that it captures the crack path and any potential crack growth regions accurately. You may need to refine the mesh near the crack tip for better accuracy.

* Enable the XFEM capability in Abaqus and define the XFEM parameters such as the enrichment type (e.g., crack tip or cohesive zone enrichment) and the enrichment size (e.g., element size near the crack tip).

* Specify the loading conditions for your analysis, including the cyclic loading pattern and the stress levels applied during each cycle. Ensure that the loading conditions are representative of the high cycle fatigue regime.

* Determine the crack growth criterion for your analysis. This could be based on stress intensity factors (SIFs), energy release rate, or other fracture mechanics parameters. You may need to use user-defined subroutines to implement the crack growth criterion.

* Implement a fatigue crack growth model in Abaqus that accounts for the cyclic loading conditions and the crack growth criterion. This could involve defining a crack growth law and specifying the parameters for crack growth rate calculations.
