In our pipe support evaluations we've always considered friction for all load cases, both static and dynamic (including waterhammer, global vibrations etc). We do feel that this is quite conservative, but haven't found a convincing argument to reduce this assumption. Now we've found that...

Thank you for your good answer mrgoldthorpe! I've tried increasing the last value of my elastic-plastic material as I realised that the stresses close to the crack tip were acctually larger than my last plastic data point. This did however not have an impact on the results. I guess I'll just...

Hi all, I am working on a pretty basic J-integral problem on a 2D geometry. I have been told that the J-values should be path-independent even inside the plastic zone in ABAQUS. However, I get path-dependent values of J on all contours inside the plastic zone, I was therefore wondering whether...

I've gotten crashes while trying to seed using Python scripts. As I have understood it it has to do with how I choose the lines to seed in the code. Depending on how you seed (by number or bias) you should choose the lines in differnent ways. For byNumber the lines should be in a sequence...

Never mind. The integration points are ordinary Gauss points. Just had a problem when reading data from the odb. I think the cause is that when using nodeDataLabel the list of nodes is automatically sorted. Hence, I didn't have the nodal coordinates in the correct order when trying to calculate...

Hi everyone, As I mentioned in a previous thread, I am trying to create my own J-integral post-processor. I've managed to create a script that creates the contours which was my first problem. At first I assumed that the integration points in ABAQUS were ordinary Gauss points, and hence created...

Thanks for your tip zubaj, Yes I'm using Python scripts in the CAE. I would preferably have a method that doesn't require any alterings to the main model. I was planning to make a routine that works with any crack model. I've found out that you acctually can find the node sets ABAQUS creates...

Thank you for your help truckcab! I've found the display groups as well and have been playing around with them a bit in order to understand how they work. I can't say I understand them completely yet, but I at least have some insight as to how they work. There have been some changes in my work...

Thank you for your reply truckcab! For pre-processing I use Abaqus CAE, and I use Viewer for post-processing. I know how to make sets out of edges, faces and vertices in the CAE. But I'm afraid that doesn't help me atm. I would like to find a way to assign specific elements to different sets...

Hi everyone, I am trying to implement a modified version of the J-integral into ABAQUS, and as I am quite new to the program I have loads of problems. :-( I thought the best way to go about doing this would be to make a Python script, as I have no experience with Subroutines or Fortran. The...
