xfem or extended finite element method in abaqus

[@rasoolmokhtarihomami9169]

Thank you very much for your great explanation.

[@kennethadams4139]

could you please explain how to derive the fracture energy?

[@FemexIran]

Hi.
Fracture energy is equal to the area underneath the traction-separation curve.
Its unit is equal to N/m or J/m^2.
For this tutorial, I used the value mentioned in the reference paper.

Very good

[@FemexIran]

thank you so much.

[@hassansayahpour2788]

very good.

[@gholamrezamohammadi9851]

hi Amir
could you possibly make a video to teach us how link abaqus with matlab?

[@prashantverma6322]

how can i find SIF with crack growth?

[@FemexIran]

Hi.
If you are using the XFEM, You cannot have the crack growth and SIF calculation simultaneously. To calculate the SIF, the crack must be stationary and it cannot growth.

[@ammaralhajri]

@@FemexIran Isn't possible to do it in a stepped way?

[@FemexIran]

@@ammaralhajri Hi.
Unfortunately I have not used this idea before.
I don't know whether it leads to accurate results or not.

[@rahulsrivastava511]

can you give me a details about your paid course.like what will you give in paid course and how much you want for that.

[@FemexIran]

at present, we do not have any paid course. we have another paid services. they are explained in the "about" section of our youtube channel.

[@rahulsrivastava511]

sir, please tell me that how we can define the enrichment nodes or enrichment region.and how we can calculate the Fracture energy.

[@FemexIran]

for answering these questions, you can use our paid services. our paid services are explained in the "about" section of our youtube channel.

Salam brother,
How to find out plasticity property like to many yield stress and plastic strain for isotopic material to give input in Abaqus ?

[@FemexIran]

hi. by searching in papers or other documents or conducting tensile test.

[@md.marufulalam9823]

Brother , is it necessary to input plasticity data?

[@FemexIran]

@@md.marufulalam9823 hi. if the material is ductile, you must define the plastic behavior. if the material is brittle or close to brittle, there is no need for defining the plastic behavior.

[@md.marufulalam9823]

FEMEX Brother ,in my case the isotopic material which I used is epoxy resin. Is it brittle or ductile?

[@FemexIran]

@@md.marufulalam9823 epoxy resin has cohesive mechanical behavior. it is not ductile but it is not brittle too. it has elastic and damage domains.
