Compatibility: Surface-Based Cohesive Behavior in UEL

Hi all,

 

I have been trying to model the surface interaction between two blocks of material using surface-based cohesive elements (*cohesive behavior). This works well in ABAQUS CAE (standard) when I set the material properties as "Mechanical, Elastic" so no problem with that.

However, I would now like to use the material properties from a fortran code. To do this, I was planning on defining the elements using *UEL with an overlay to record all the values. Is this compatible with cohesive zone elements? 

 

Recover wall clock time in Abaqus/Explicit

Dear All,

Does Anybody know how to recover the wall clock time of an Abaqus/explicit analysis? I do not understand why for implicit analyses is easy (log file) while for explicit there is no information.

Thank you,

Mauro. 

Rotational Abaqus Direct Cyclic Boundary Condition

Greetings,

I am attempting to model the rotation of a cylindrical bar using Abaqus 6.12 coupled with the direct cylic approach. In my model I have one end of the beam fixed while the other has a kinematic coupling constraint to a reference point that has an applied rotation of 0.1 rad.

Hello everybody

Create new ( multiple ) parts from existing (single )part in Abaqus

Hello Everyone,

i am kind of newbie to Abaqus, in learning phase. My question is regarding creating new parts from existing part in abaqus, kind of splitting activity similar to slice feature in ANSYS Designmodeler. As far as my regular activity in Ansys workbench, i require to slice body in designmodeler, to create new volumes, to refine mesh, or to define contacts with different status.have limited access to modeling software, so basically work with simulation software pre processor.

YOU COULD WIN: The Look What I Did Challenge

As we approach the last few months of 2013, it’s interesting to
reflect upon what took place over the past ten months. Reminiscing can
be fun, but do you know what makes it even better? Sharing memories for
prizes!!! This month we are launching a new contest and here is how it
works…

how to model masonry wall in abaqus

here we are to tell you how we can model masonry in abaqus cae.

there are 3 ways:

1-micro modeling

2- macro modeling

3- micro-macro modeling(HOMOGENIZATION)

micro modeling; 

in this method all parts should be modeled in abaqus separately.

but notice that don't use shell to modeling grout because of 3d properties of grout and cohesive characteristics.

this method is suitable for small masonry panels with 2-3 layers of brick.

how to link abaqus with matlab ?

You should access the abaqus results (*.fil) file via MATLAB.

In order to take your results into a fil file you should specify
*FILE FORMAT, ASCII along with *EL FILE and/or *NODE FILE, etc. options
in your abaqus input file (assuming that you run Abaqus/Standard).

Abaqus python scripting, booleanmerge section assignment

Hey,

 I am writing a python script for modeling aggregates in a concrete cylinder. I have created a all the particles and and specified section properties to them and to the  cylinder.

The procedure I am using is to merge the particles and the cylinder while retaining the boundaries. If the sctions are assigned to the parts before merging, the result is the cylinder with the specified section assignmentsfor each part.

I wrote the code in python but seems like it does not include the section assignment to the new part from merge.

PhD studentship position on "modelling of surface defects transformation in hot rolling of steel"

a PhD student ship is available for UK/EU nationals (ONLY) to develop a Finite Element model of the rolling
operation to predict the behaviour of surface defects on the rolled
material during hot rolling of steels. The effects of geometrical parameters along with the material
properties and the rolling geometry, such as bite angle, on the behaviour of
the surface defects during rolling will be investigated. The
project is partially funded by Tata Steel Europe,

ainsotrpic plasticity in Abaqus

Hello

 

Does anybody know how to input ainsotrpic plasticity in Abaqus?

I have an orthogonal elastoc plastic material and to input elastic properties I use engineering constants but to input orthogonal plasticity (not for all components)  I have no clue.

 

Thnaks in advance,

A Very silly abaqus question... applying a wind load

Dear All,

Sorry to ask such a silly question but I am quite new to Abaqus... I am trying to model a tower exposed to wind. I know how the wind pressure varies according to height, but what I dont know is how to model it in abaqus... Also, if i apply a pressure load, then the load will act normally at all points on the surface, right? But in actuality wind doesnt act that way... Could anyone help me out on this one?

 

Thanks and Regards,

Lekshmi 

Problem Modeling JKR contact using Abaqus

Hello Everyone,

I have been working on solving contact problems relating to fibrillar adhesives over the past 3 yrs of my PhD work. In the past, I used Comsol FEM to model contact interactions by implementing the Dugdale-Barenblatt traction separation law at the contact interface.

Abaqus - Please help!

Hello,

I am a bit confused about a simulation of brittle cracking presented in "ABAQUS EXAMPLE MANUAL" 1.1.5 Collapse of a concrete slab. I was trying to re-simulate the example on my PC and I got really weird results force (RF3) vs. time read in the support point.

Please have a look at attached picture. I download the file mnneice_5.inp from Example 1.1.5 calculated and got totally different resuls. Does it have something to do with setting of my Abaqus software?

Can somebody do the same and check this out?

 Thank you very much for any help!

high strain rate simulation in abaqus

can anyone tell me how to perform high strain rate simulation in abaqus.

Submitting number of job at once in Abaqus

To solve several consecutive run automatically by abaqus can get help from the following program:

http://mmd110.persiangig.com/Abaqus/abqscript.bat

First file in the file path. Inp place available.

Then run the file name. Inp file and cpu, and the amount of RAM required by the MB session.

Inp file name (without extension and tandem) and enter them below, separated by a space.

Note: Before entering the first name inp file, insert a space.
