Hi all,
I am currently in my second year in Engineering school in France. I am doing research on 3D crack propagation in Rubber composites like tires.
And I wonder what is the best method to compute GI, GII and GIII. I have difficulties to choose between methods like EDI and VCCT for example.
I work in the finite strains case with static and dynamic. I also have difficulties to find papers on this subject with comparisons.
Can anyone please help me out with that
Thank You
Best Regards
[Abaqus] How to measure the distance of failed cohesive elements (crack length) from load line for every time increment?
Forums
Hi
I have a working DCB model with embedded cohesive elements. This is done in Abaqus/CAE standard using nonlinear analysis.
However I'm having trouble finding an efficient way of measuring the distance of failed cohesive elements from the load(displacement) line for evey time increment in abaqus. Its possible to do this manually using the 'Query information' tool for every single time increment but for a model with more than 100 frames this method is not very good.
Phase Field Modelling of Fracture Mechanics
Forums
Hello To one and All,
I am currently working on my Master's thesis in Computational
Mechanics and as the Title suggests, I am working on using phase field
theories to model fracture mechanics. The whole idea /concept of phase
field modelling in itself has been a very complex topic for me, as it
originates in superconductivity theories of which I have but a
superficial understanding. I am ok with fracture mechanics terminology
as I have worked on it before.
Abaqus UEL subroutine help
Forums
Greetings to all Imechanicans ! ,
I just started using the scripting interface in Abaqus, and i stumbled into a small issue, I have a sample input file which is a small model for crack simulation and its UEL subroutine, I know how to open the input file but I don't know how to open the UEL subroutine that goes with it, I get the following error :
The model "projGH" has been created.
modeling corroded pipe with Abaqus

Hello everyone,
I'm doing a 3D modelingcorroded pipe. The results is differant from the Analytical solution (modified N31G mathod). Abaqus results is actualy half of the analytical solution.
I need some help whith:
1- Half of the pipe was modeld so, how should i constrain the pipe? I constrained it as in the attached picture.
2- How can i know how much load was applyed?
3- how can i magnifiy teh displacment?
Thank you,

anaylsis of cutting tool wear with coatings in orthogonal cutting
Forums
Hi,
Can anyone discuss about, how can we simulate tool wear on coated/uncoated cutting tools in orthogonal turning using Abaqus. Any suggestions/links would greatly appreciated.
Thanks and Regards,

simulation of compact tension tests

I am a student and I need to simulate compact tension test so as to obtain the fracture toughness using ABAQUS. I would have to compare the fracture toughness value from ABAQUS with values obtained from experiment.
I have been trying to model the compact tension test for weeks without sucess. Can anyone give me the step by step description of how to model the compact tension test
Thank you
Looking for some references about damage mechanics!

crack propagation and cohesive elements in Abaqus
Forums
Hello,
I have been reading up a lot 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 for a kind of "Introducing modern science to the public" exposition... I am trying to simulate crack propagation in rubber material in the case of uniaxial tension.
I recall the problem that i want to simulate:
