I think I should use pure Eulerian model. Since the particle and substrate are not rigid and they deform excessively under impact.
So this time I define 3 Eulerian Part (Substrate, sphere particle and Eulerian domain).
I meshed all parts and assigned Eulerian section to all parts.
Also defined...
Dear All,
I want to model the metal particle impact (at high velocity) on to a metal substrate (cold spray process).
Due to excessive deformation I have to use Eulerian method.
So I would like to know how should I make this model. I did as bellow but my model is not working!
I defined the...
Thanks for your answer.
Is there a way that I can find maximum stable increment size that give me accurate results?
I should explain more what I am doing:
I have an experimental thermal history from a thermal spray coating process. The aim of simulation is finding the amount of unknown heat...
Dear FEA way,
Thanks for your answer.
I have some more questions:
1- According to my simulation the highest temperature with increment size of 0.01 is about 1100°c. Is it ok to set DELTMX 2000? Or I must choose even lower?
2- About increment size: you say better to check lower inc. size, you...
Dear ABAQUS users,
I have a question regarding increment size.
I ran a model with 2 different increment size: 0.05 & then 0.01 (initial & max increment size), the minimum increment size are the same for both case and it is 5E-11.
But I got two different results (thermal history).
The model is a...
Yes it works without individual property assignment. But with separation properties, I need no separation in my model, so I must use individual property assignment for that.
The files for warning are attached...
Ok, Thanks a lot for your helpful comment.
I run the model but at the end I cannot see the results on deformed shape. The message that appears is attached.
What I have done is:
I used "general contact"--> "Global property assignment" --> "All with self" with separation behavior. And...
Hi,
Ok, so as I understood I have to define global property (general contact--> All wit self), without the no-separation behavior.
1- Then I have to define surfaces for each particle and then at Individual surface assignment I have to select each two pair that have contact with each other, yes...
Dear FEA way,
Thanks for your answer.
I also tried it. You mean don't define a Global property assignment and just define Individual property assignment. I am right?
I did it. Since I have a lot of particles I cannot define individual surfaces for each of them, so I select Global and Self in...
Hi
I want to simulate multi particles impact in cold-spray process.
I have used:
Interaction: General contact
Contact domain: All with self
Contact properties: Tangential Behavior, Normal Behavior and Thermal Conductance
Uncheck "Allow separation after contact" in Normal Behavior,
But the...
Yes, but I was not able to use AM Plug-in 2022. It was the reason that I replaced it with 2018.
Do you think it is the reason that the temperature of the model is not raising up?!!
Dear FEAway,
Yes, I am using ABAQUS 2022 golden. But I changes the AM Modeller plug-in to AM Modeller plug-in 2018 (because the AM Plug in of 2022 was difficult to understand).
Dear FEA way,
Here is also .jnl file. In case is needed.https://files.engineering.com/getfile.aspx?folder=af99f996-48f5-4c50-8789-fa788826e947&file=Thermal-Mechanical_AM_Model-ZA(jnl).zip
