Joint elements in ABAQUS to model discontinuity in rock

Submitted by Kazem Ghabraie on Tue, 06/24/2008 - 05:36

I am trying to model a rock mass with few discontinuities in ABAQUS. I have to use "joint elements" (Goodman element or the more recent variations) to model the discontinuity. The element should model a separation in tension and a slipping governing by Coulomb friction. Is there any element in ABAQUS capable of modeling such behaviours? If not how can I add one?

Thanks,

Kazem

Plasticity Model for Autofretage of a Cylinder in ANSYS

Submitted by Himayat Ullah on Tue, 06/24/2008 - 05:36

Cyclic Plasticity

Dear All,

I am analyzing a steel pressure vessel with autofretage effect in ANSYS. This effect brings the vessel steel fully plastic in the first load step.After the remval of the load in the second step,a permant strain and residual stress remains in the vessel.The residual stress develops compressive stress in the vessel.

SIF in ANSYS

Submitted by Fattaneh Morsh… on Mon, 06/23/2008 - 10:15

To calculate stress intensity factor ANSYS have two option:

1. Plane stress

2. Plane Strain

In a completely 3D problem, How can I use ANSYS to calculate stress intensity factor with out using J integral?

Need tutorials and macros related to piezoelectricity using ANSYS

Submitted by S Premkumar on Sun, 06/22/2008 - 16:38

Hi,

I recently started working with piezoelectricity using ANSYS. Can anybody suggest me some tutorials and macros for ANSYS-piezoelectricity.

Artificially High Read Counts

There has been some discussion about the low ratio of replies to reads on iMechanica. While it's nice to think that a lot of people are reading our posts, I wonder how many of those 'reads' are really bots indexing the page. For example, I posted a blog entry last night around 11:00 and nine hours later it says it has been read 45 times. A couple of those can be attributed to me but I'm sure 40 real people have not read the post. Add to this the fact that the post is already showing up in Google.
