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,

Srilatha

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.

 

Compressive Strength of Fabric??

Submitted by fea on

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

Submitted by Julien Jonvaux on

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.

abaqus drilling

Submitted by Sameer_Shah on

hi...i am doing drilling simulation on abaqus.... 



it consist of two parts...a tool and a blank.... 



now when i am running analysis...tool touches the blank and goes back. 



i checked material data...density,elasticity...and i used surface to surface interaction with penalty as interaction property.... is there any other data that i need to include....???if yes then how....



can any one tell me ...
