Comprehensive Abaqus Package: • Comprehensive Abaqus P...
Including 39 hours of step-by-step tutorials.
Don’t hesitate to ask any questions you might have about the explanations presented in this video using the comments below. We try to answer all questions regarding the video details in the comments below.
The Contour Integral and extended finite element methods (XFEM) are two methods for calculating stress intensity factors and J-integrals in Abaqus.
In this tutorial, The calculation of the J-integral in the Compact Tension specimen via Abaqus using the Contour Integral method in 2D and 3D spaces is explained according to a paper.
The complex procedure of creating a focused “spider web” mesh with elements concentrated at the crack tip is explained in detail. In addition to using an appropriate mesh pattern, the crack singularity settings are done to finally obtain the most accurate answer without generating too many elements in the crack tip region to reach accurate results.

Very practical and useful tutorial👍 many thanks🙏
Thank you so much.
why do my contour integral objects contain regions that cannot be mapped into layers of node sets?
Hi.
Please send an email to me to resolve that issue.
My email: mirzabozorg71@gmail.com
@@FemexIran I've already emailed you
@@AdiraFitriaPutri-tt7uz Thank you. Yes I received it.
why my j integral contour is not converge as contour number increase
Hi.
Good day.
There can be several reasons:
1) The size of each contour is not appropriate. The focused mesh must include the plastic region entirely.
2) The singularity settings are not correct.
3) You have not generated the focused spider-web mesh pattern appropriately.
You can buy the extended premium package of this tutorial to learn how to do the contour integral analysis appropriately. Also you can use the discount code to buy it with 50%discount. This is the link to the discount code explanation:

can we apply load in terms of incremental displacement ?
Hi.
Yes I have done the same.
@@FemexIran is displacement applied to the periphery of the hole?
@@SubhamPrasad-rf1hq Yes. It is. The displacement is applied to the RP at the center of each hole and the perimeter of each hole is coupled to its relevant RP at its center.
Sir can you share the material properties
Hi.
Please send an email to me: mirzabozorg71@gmail.com
@@FemexIran I have sent the mail sir
@@ramasamiregeshk8875 Yes. Also you sent a message to me on telegram and I have answered it.
May I ask you that sell it to me, in friendly way and select my payment?? Majidian
Hi.
I told you the price of this tutorial previously on telegram. I cannot decrease it for you more.
