Abaqus Fatigue Tutorial
Fatigue in Abaqus has been a tricky problem for simulation. You will learn how to perform the fatigue crack growth(FCG) simulations using the Paris law of fatigue crack growth. A 2D planar shape and a 3D-dimensional model crack growth problems are solved to propose the Extended Finite Element Method (XFEM)approach in this Abaqus Fatigue Tutorial. What’s more, you need to define the fracture criterion as a keyword for your model, as a result, you will get familiar with how to edit keywords in Abaqus. You also discover the Paris law equation of FCG which takes into account the mean stress effect. Furthermore, you will get a full explanation of the Direct cyclic Step. Last but not the least, you will analyze the Maxps damage initiation criteria to use to predict damage initiation in the XFEM enriched region. All in all, you will get the knowledge to create step-by-step 2D and 3D XFEM fracture models using Abaqus software.
Workshop 1 crack growth of a 2-D problem using XFEM Fatigue:
In this chapter of Abaqus fatigue tutorial, we go through the simulation of fatigue by a 2D planar deformable model. You will use constant amplitude loading to predict debonding growth at the interfaces in low-cycle fatigue analysis. Moreover, damage modeling is achieved through the use of a traction-separation law across the fracture surface.
Workshop 2Â XFEM modeling of low cycle fatigue crack growth in steel:
This tutorial is about predicting fatigue crack growth life under constant amplitude loading through the Extended Finite Element Method (XEFM) for a 3D steel model. You will design a 3D model and a crack in the middle of one edge and predict how the crack grows through the part. You will get a full explanation of fatigue in the Abaqus Documentation.

In social media, users asked questions regarding simulation of fatigue in Abaqus. We answered some of them, which you can see below:
I. Low cycle fatigue analysis
Q: I’m doing an LCF in Abaqus and used the Paris law to calculate the values of C3 and C4. How to find C1 and C2 values or where to find them..?
What will the value of power (BK or power-law) be?
A: Hi,
I hope you’re doing well. Generally, some specific parameters and material properties are nowhere to be found except:
- You search and find them in the articles and previous works that have been done by others.
- Search in the manufacturing companies and may find what you’re looking for in their websites and datasheets.
- Or you do an experimental test by yourself according to the standards.
You may find something by doing a simple search on the web, but the best ways to find these sorts of parameters are the ones I have told you.
Also, I suggest checking this blog:
you may find something useful in it. It is worth it.
Best wishes.
