do you mean the very thin white line in the upper side of the gap?

I got problems similar to yours. I can't obtain a reasonable force vs displacement curve with reinforced concrete elements. Moreover, even increasing the lenght of the step time, the kinetic energy is "jagged", because it dosn't vary smoothly during time. Even on this forum, I couldn't find...

there is a particular kind of element in the middle of the specimen? Such as cohesive layers etc. ?

This is the getting started for Abaqus 6.12: http://www.maths.cam.ac.uk/computing/software/abaqus_docs/docs/v6.12/pdf_books/GET_STARTED.pdf

In the Abaqus getting started documentatio, there are basic informations about quasi static analyses, read it! If you have other doubts, ask us! ;)

Hi guys! I'm trying to model a part of a precast reinforced concrete structure, a beam and a column tied together with dowels. I must obtain a result very similar to an experiment performed by the university laboratory. I'm using Abaqus/Explicit, because with Abaqus/Standard I have numerical...

Hi Guys! I'm trying to model the contact between 2 surfaces using a cohesive layer with a traction-separation law. I want to use a bi-linear constitutive behaviour, like the one reported in the image I attached; that bi-linear diagram is completely known to me. The behaviuor is the same in...

Thank you very much!!! :)

ok thank you! So if I don't choose that option, will Abaqus use only one of my 4 cores? And if I want to use all the "power" of my computer, do I have to select "4 processors"?

Hi Megabeast! I intended that the preload should determine a curtailment of the bolt, and not an elongation of it. I said it because, the very first time I used the bolt preload, I used an uncorrect sign of the load, and it can be a common error for new users. If I can give an advice, try to...

Hi guys, I've got a question about the definition of a job in Abaqus. When you define a job, in the Parallelization section there is an option: "use multiple processors". What does it mean? It's this thing related with the type of processor of my computer? (I've got an i7-4870HQ, quad core...

PS In the "job" module, open the "job manager" and click "submit". After this, click "monitor", to monitor the process and see in which step the program has "troubles" to solve the problem

Hi! first of all, it's not necessary to define manually the pairs of surfaces that can be in contact. Moreover, you can use the first 3D model of the bolt, it should work. Follow these steps and let me know if the analysis will end correctly. 1) During the "geometric definition" of the model...

Thank you! I didn't know that there was such a topic in the "Abaqus Getting started". I'm going to study it! [thumbsup]

Hi guys! I'm trying to model a bolted connection in Abaqus/standard. I have to perform a static Analysis, but due to the high number of contact interactions, the analyses are sometimes impossible to perform (aborts due to errors, physically meaningless results). So, I decided to use...

Take a look at this! http://www.oulu.fi/tietohallinto/unix/abaqus_docs/v6.13/books/gsa/default.htm

Hi guys! I need help for a problem with the modeling of the material behaviour. I want to use two different σ-ε diagrams, for traction and compression, to model the steel material. How can I do that in Abaqus? It seems to me that it's possible only with certain models with concrete, but not...

Thank you so much guys! I used the solution proposed by WayneKagawa because it seemed to me simpler; in fact, I prefer to use the graphic user interface, rather than the "command line" Bye! :)

Hi everybody! I've got a problem in calculating the reaction forces in Abaqus. I assigned a boundary condition (U1=0 U2=0 U3=0) to a cylindrical surface; a high number of nodes lies on this surface. I created a set (based on the geometry) that consist of this surface, to have the possibility...
