    Self healing or blocking of polymers.

    I was trying to model an application where I need to model a silicone that has a slit in it. The slit is under pressure and after a certain time and temperature the slit heals / cures and blocks. Any ideas??? Ideally what I would like to have is to be able to give some properties to the slit...

    Thermal Analysis of a Laser Weld Process

    The Solution to my Problem :-) Temperature activation and deactivation of elements diretly in ABAQUS is not possible. The work around for that is: 1) Run your analysis in steps. 2) After first step is over, use abaqus scripting to create a script that will identify elements that have reached...

    Adding elements in CAE

    Hello Antonio, I just wanted to tell you that I might have a solution to a lot of your problems. 1) Adding Elements: You can use the *MODEL CHANGE command in CAE by using Edit Keywords option. Go in the pull down menu - MODEL - EDIT KEYWORDS and select your model. This will open a window...

    Abaqus Scripting interface

    Hello, I needed some help in the Abaqus scripting interface. I have a .py file from odbAccess import * from string import * odb = openOdb('Analysis.odb') FirstLoadStep = odb.steps['Rise'] print 'First Load Step',FirstLoadStep lastFrame = FirstLoadStep.frames[-1] #print 'lastFrame',lastFrame...

    Thermal Analysis of a Laser Weld Process

    Hello AntCrespo, Thanks for your inputs. I was able to reduce the temperature by just lowering the energy input. This is inline with the assumption that in a laser welding process depending upon the material and the surface being welded only a certain amount of energy is absorbed by the...

    Thermal Analysis of a Laser Weld Process

    Hello AntCrespo, I rang up Abaqus support and they could not solve my problem either. Giving my problem a second thought, I just felt that I need not have to do anything. I was trying to restrict the temperature of the nodes to 1600 which was the melting point. However in reality the material...

    Thermal Analysis of a Laser Weld Process

    Corus, Thanks for the idea. But how do I do that. I mean if I use *MODEL CHANGE, then I have to define the elements which I need to deactivate. Is there some way that I can do it automatically as soon as the NT reach 1600. I would have to run the analysis in various small steps and then find...

    Thermal Analysis of a Laser Weld Process

    Hello, I am a new user of Abaqus and I was really amazed and happy to see this forum. I hope to get some help from it too and I promise to help people when I am in a position to do so. I am trying to perform a Laser Weld Process Simulation on Titanium. I was wondering how to apply the loading...
