Hello,
I am expected to calculate strain energy release rate for a single lap composite joint using VCCT in ABAQUS.How do I go about it?
The manual saya some thing about debonding? How do i do that in my model?
Thanks,

Hi everybody,
I'm looking for some resources (textbooks,webpages,papers) to give me some insights into stress analysis and fracture mechanics of functionally graded materials. i appreciate any suggestions.
Thanks.
Cracking option in ABAQUS
Dear All,
I am modelling the cracking in concrete in Abaqus CAE using the Brittle cracking option in Abaqus.
Now i want to see the output results (Contours of cracks) like CRACK, CKE, CKSTAT etc.
But i dont know how to see that output
Can some one help me
Thanks
Kind Regards

Compressive Strength of Fabric??
Choose a channel featured in the header of iMechanica
I am trying to model a rubber impregnated fabric as rebar in Abaqus Standard. It seems that the rebar is only good in uniaxial tension load and it causes convergence problem in bending and compression loading. The fabric and rubber matrix has a compressive strength and that is critical to the model that I am analyzing. What would be a good approach to include compression on fabric rebar? The compressive strength of fabric matrix should be an order of magnitude lower than the tensile strength but I do not have a test data in compressive loading.
Stress intensity factors for a slanted crack under compression
Hello everyone,
Here is the problem I have: I'm modeling the geometry of a simple straight edge crack in a 2D elastic medium using Abaqus. I assume plain stress conditions. The crack makes an angle with the horizontal, is small enough to be considered as embedded in an infinite domain (ratio crack length/size of domain < 1/10) and I apply a vertical compressive load on top of my domain. I fixed one point in displacement at the bottom of it and the whole bottom edge is constrained not to move vertically.
Laterally loaded pile groups
Hi, I am Ramy, I am about to perform some analyses on laterally loaded pile groups in sandy soils, does anyone have any idea about the best constitutive model to use?, loading is static. And I am using PLaxis 3D foundations version 2.1 Regards, Ramy
