First of all let me tell you how i compute the deformation gradient. I wrote a UVARM subroutine in which i call the deformation gradient. Throughout the rest of this comment this is the deformation gradient i am refering to. You can see below what i a talking about:
CALL...
Hi everybody,
I am trying to model an anisotropic hyperelastic material in plane stress under uniaxial tension
where W=Wiso +Wani= C10*(I1-3)+C4*(I4-1)2 .
When the load is parallel or perpendicular to the fiber direction, the deformation gradient returned by Abaqus matches the theoretical...
Hi,
According to you the damage criterion is not met.
I am going to work on this using SDEG.
My last question is more about the geometry itself.
Indeed i just created one single geometry that i partitioned to account for the interface. So i basically created one single part.
Should i create...
Hello,
I have been working for two days on my model and i made some progress in the process of understanding "crack propagation" modeling in Abaqus but i didn't get what i was looking for. Indeed no crack propagation occured ...Frown
The idea is to define the crack tip as the zone where...
Hi,
I took your advice.
For the rubber part i defined an elastic behaviour (small strain problem) and a Solid Homogeneous section that i assigned to the bottom and top parts.
Then i defined a second material:
- Elastic --> Traction (E=200 000 Abaqus Unit System, Poisons's ration = 0.45)
-...
Here is a picture of the model with an interface sketched to account for the crack path.

Hi everybody,
I read up more on "crack propagation" and "cohesive elements" in Abaqus. But i am still struggling to make it run and frankly i am running out of time. I have got only two more days to get the model running...
I recall the problem that i want to simulate:
A piece of rubber...
Sorry i forgot to attach the pictures:

Hi,
I read up more on "crack propagation" and "cohesive elements" in Abaqus. But i am still struggling to make it run and frankly i am running out of time.
I recall the problem that i want to simulate:
A piece of rubber (hyperelastic neo-hokean) material is subjected to static uniaxial...
Dear Amubashar,
How can i make use of these types of elements to simulate "crack propagation"?
To be honest i never used such elements but according to you they might be useful to me.
What are "cohesive zone elements" regarding crack propagation? I aim at modeling a rubber material...
Hi everybody,
I am trying to simulate crack propagation in rubber material. As you can see in the attached pictures, i aim at trying to propagate the crack along the horizontal line.
I have browsed through the help and found out that ther is a feature called "Debond" that permits crack...
Hi,
I am trying to model a penny shape crack in a 3D model (see pictures attached in the Power Point Presentation). To sketch the crack I use the "Shell ---> Revolve" featured function" of Abaqus.
Indeed I sketched a line that I revolved (by a 360 angle) with respect to the axis of revolution...
Hi everybody,
I would like to create a contour and compute the contour integral of the Eshelby Tensor (computed through a UVARM subroutine) along that path (see attached picture).
Here are my questions:
1 -- Is it possible to define a contour in Abaqus so that Abaqus will be able to identify...
